Summary

Hot melt packing tape is a packing tape made of polypropylene (PP) film that is coated with a hot-applied hot melt adhesive based on synthetic rubber. It bonds instantly when pressed down, needs no drying or curing time, and is the best-selling tape for carton sealing in shipping. In this guide, you'll learn how hot melt packing tape is constructed, how it's made and when it's the right choice – and when you're better off reaching for a different tape.

All technical values in this article come from the current data sheets of our PP packing tapes (as of 08/2026). Wherever we quote general guideline values from packaging practice, we say so explicitly – so you never confuse data sheet values with rules of thumb.

Chapter 1 · Basics

What Is Hot Melt Packing Tape? Definition and How It Works

Hot melt packing tape (also called hot-melt tape, hotmelt packing tape or PP packing tape with hot melt adhesive) is a self-adhesive packaging tape for sealing cartons. The term, however, doesn't describe the film – it describes the adhesive: a hot melt is a hot melt adhesive that is applied to the backing film hot and liquid during manufacturing and solidifies into a permanently tacky layer as it cools – entirely without solvents or water.

The crucial difference from hot glue out of a glue gun is that the hot melt on packing tape stays pressure-sensitive after cooling. Experts call this a pressure sensitive adhesive, or PSA for short. So the tape never needs to be heated – it only needs to be pressed down. Under light pressure, the adhesive flows into the pores and fibers of the carton surface and anchors itself there within seconds.

The backing material is a PP film made of polypropylene. During manufacturing it is stretched lengthwise and crosswise, which makes it extremely tear-resistant and at the same time stretchable at a thickness of just 25 µm. The combination of PP film and hot melt adhesive has been the standard for packing tape in mail-order shipping for decades, because it unites three properties that usually contradict each other: high adhesive strength, high processing speed and a low price.

On the market, you'll find the spellings hotmelt, hot-melt and hot melt side by side. They all mean the same product. At Tapemonster it's available as PP packing tape with logo (standard, loud unwind) and as a reinforced, quiet-unwind version under the name Super-Melt packing tape.

How the Bond Works

Hot melt doesn't stick because it "dries" – it sticks because it flows. The adhesive layer behaves like a very viscous liquid: firm enough to stay on the roll, yet soft enough to conform to every bump and dip under pressure. Three things happen in quick succession:

  1. Pressing down

    Your thumb, the pressure roller on the dispenser or the roller of the case sealer presses the tape onto the carton.

  2. Wetting out

    The adhesive flows into the rough, fibrous surface of the carton. The better this wetting, the larger the contact area.

  3. Anchoring

    Adhesive forces between adhesive and carton plus mechanical interlocking in the fibers hold the seal. Full ultimate adhesion is reached after a few minutes.

The second half of the equation is cohesion – the internal strength of the adhesive layer. It ensures that the tape doesn't "flow apart" under tension and that the adhesive doesn't stay behind as a smeary film on the carton when the tape is pulled off. A good hot melt formulation balances tack (initial tackiness), adhesion and cohesion so that the tape grabs instantly yet still holds up under load.

The Six Biggest Advantages of Hot Melt Packing Tape

01

Instant Adhesion

Press it down, done. There's no waiting time during which the carton has to sit still. That's why hot melt is the standard tape for packing lines and conveyor belts, where every carton goes straight on to shipping.

02

Strong Adhesion to Cardboard – Including Recycled Cardboard

The rubber adhesive wets out rough, fibrous and slightly dusty surfaces better than water-based acrylic adhesives. On corrugated cardboard with a high recycled content, that's the decisive advantage.

03

Tear-Resistant and Stretchable

According to the data sheet, the PP film reaches an elongation at break of 160 %. When a package takes a knock in transit, the tape gives instead of tearing – the carton stays shut.

04

Machine-Compatible

Hand dispensers, tabletop dispensers, semi- and fully automatic case sealers: hot melt packing tape unwinds evenly and tolerates high processing speeds. Standard core 76 mm (3"), standard widths 48 mm (1.9") and 50 mm.

05

Solvent-Free and REACH-Compliant

Hot melt is processed as 100 % solids – no VOC emissions, no solvent smell while packing. According to the data sheet, the tape contains no hazardous or harmful substances and complies with REACH Regulation (EC) No. 1907/2006.

06

Inexpensive and Excellent for Printing

Among packing tapes, hot melt offers the best value for money. The smooth, corona-treated PP film takes flexo printing ink cleanly – ideal for packing tape with your logo.

Where Hot Melt Packing Tape Reaches Its Limits

Heat, UV and Long Storage Times

  • Heat: Above roughly 60 °C the rubber adhesive softens – an attic in midsummer, vehicles parked in the sun or cartons right next to a radiator are critical.
  • UV and outdoor use: Standard hot melt ages under sunlight; adhesion fades over time. For outdoors, PVC tape with natural rubber or acrylic tape is the better choice.
  • Long-term storage: For cartons that will sit sealed in the warehouse for longer than about 12 months, we recommend more aging-resistant adhesives (acrylic or natural rubber).

Cold, Noise and Food

  • Cold during application: Below about +5 °C, initial adhesion drops noticeably because the adhesive becomes too stiff to wet out the surface. In cold storage, natural rubber has the edge.
  • Unwind noise: Standard hot melt unwinds loudly – no big deal in the warehouse, annoying at a packing station in the office. That's what quiet-unwind versions like our Super-Melt are for.
  • Food: Our packing tapes are not intended for direct food contact. For the outer carton of a food shipment, that's not an issue.
Chapter 2 · Construction

Construction and Composition: What's Inside Hot Melt Packing Tape?

Hot melt packing tape consists of just three layers, together thinner than a human hair. Yet every layer carries a piece of materials engineering that decides whether your carton stays shut or not.

The Backing Film: Polypropylene (PP)

The backing film is made of polypropylene (PP) and is stretched lengthwise and crosswise during manufacturing (biaxially oriented). This aligns the polymer chains and makes the film exceptionally tear-resistant, dimensionally stable and clear at a very low thickness. Our standard film is just 25 µm thin – a human hair, by comparison, measures around 60 to 80 µm.

The film comes in the base colors clear, white and brown. Clear film shows the carton and any print underneath, white film is the neutral print surface with maximum contrast, and brown film blends in with corrugated cardboard. Before coating, the film is corona-treated: an electrical discharge raises the surface tension so that adhesive and printing inks bond reliably.

Film thickness also affects unwind behavior. A slightly thicker, stiffer film dampens the noise made when the adhesive separates from the roll. That's why our quiet-unwind Super-Melt packing tape uses a 28 µm film for a total thickness of 50 µm.

The Adhesive: The Hot Melt Formulation

The adhesive is a hot melt formulation – a blend of four groups of components that the adhesive manufacturer tunes to one another. Roughly speaking, about half of it is resin, a third is polymers, and the rest is oils and additives. The exact formulation is every manufacturer's trade secret. On our standard tape, 17 g/m² of it ends up on the film (tolerance: 16 to 18 g/m²), which corresponds to a layer thickness of around 20 µm.

Synthetic Rubber

Styrene block copolymers (SIS/SBS) form the backbone. They provide cohesion – internal strength – and the elasticity that lets the tape absorb impacts.

Tackifier Resins

Tackifying resins turn the rubber into a pressure-sensitive adhesive: they create the tack (initial tackiness) and ensure that the adhesive wets out the carton surface.

Oils and Waxes

Plasticizing oils and waxes set the melt viscosity so that the adhesive can be coated evenly at 150 to 180 °C, and fine-tune the softness of the finished layer.

Antioxidants

Stabilizers protect the rubber from aging caused by heat and atmospheric oxygen – on the roll in the warehouse just as much as in the melter during production.

Source: Technical data sheet PP Hot-Melt, loud unwind, Rev. 08/2026 (Ref. 268). According to the data sheet, the product contains no hazardous or harmful substances and is REACH-compliant.

Guideline values from practice (not data sheet values)

Application temperature: ideally +10 to +40 °C, not below +5 °C. Service temperature after sealing: about −20 to +60 °C; constant exposure above 50 to 60 °C weakens adhesion. Storage: 15 to 25 °C, below 65 % relative humidity, protected from light. These values apply to PP hot melt packing tape in general – if your application pushes up against one of these limits, get advice first or test with a sample.

Chapter 3 · Manufacturing

How Hot Melt Packing Tape Is Made: From Film to Finished Roll

Production runs fully automatically on coating lines that process film webs several meters wide. The goal in every step: a coat weight that stays the same to the gram over thousands of meters – because that's exactly what determines whether every roll bonds like the one before it.

Producing and Preparing the Film

Polypropylene is extruded into a film and then stretched lengthwise and crosswise (biaxial orientation). The surface is then corona-treated so that adhesive and printing ink bond reliably later on. A wafer-thin release coating on the back ensures that the finished tape can be released from the roll.

25 µm film · corona-treated

Melting the Adhesive

Rubber polymers, tackifier resins, oils and antioxidants are processed in a melter or extruder at around 150 to 180 °C into a homogeneous, solvent-free adhesive mass and filtered before coating. There's no solvent that has to evaporate and no water that has to dry.

150–180 °C · 100 % solids

Coating (Hot Melt Coating)

The liquid adhesive is applied evenly to the moving film web through a slot die or a roll coater. Coat weight is the most important control variable: our standard tape receives 17 g/m² (tolerance 16 to 18 g/m²). More adhesive means more adhesion on rough surfaces, but also higher costs.

17 g/m² ± 1 g/m²

Cooling

The coated web runs over chill rolls. Within seconds, the hot melt solidifies into a ready-to-grab, permanently pressure-sensitive layer. Because no drying tunnel is needed, this step uses considerably less energy than manufacturing water-based acrylic tapes.

Seconds instead of a drying tunnel

Winding and Slitting the Jumbo Roll

The finished web is wound into a jumbo roll several thousand meters long. Slitting machines then cut it into the sales widths – usually 48 or 50 mm – and wind it onto 76 mm cores with a length of 66 m (50 or 100 m are also common).

48/50 mm × 66 m · 76 mm core

Testing and Labeling

Random samples from ongoing production are tested for peel adhesion to steel, rolling ball tack, elongation at break and thickness. Every delivery carries a batch code on the roll label or delivery note – since the EU Packaging Regulation PPWR, this traceability is mandatory, not optional.

ISO 29862 · ISO 29864 · rolling ball test

Printing optional

For printed packing tape, the design is flexo-printed onto the film – depending on the production line, either before coating or onto the finished jumbo roll. The flexo printing plate (cliché) is made once and kept on file for reorders. We explain exactly how the printing works in our article on flexo printing.

Why this matters to you

Consistency Beats Record Values

A packing tape doesn't need the highest adhesion value in the world. It needs to bond on roll 1 exactly the way it bonds on roll 36 – otherwise you're constantly readjusting your dispenser or finding open cartons at your customer's door. That's why, when selecting our tapes, we look at the tolerances in the data sheet first and at the peak values only after that.

Chapter 4 · Applications

What Is Hot Melt Packing Tape Good For? Applications in Practice

Wherever cartons need to be sealed quickly, reliably and in large numbers, hot melt is the first choice. Here are the typical fields of use – and what tips the scales in each of them.

Shipping and E-Commerce

The core business: sealing shipping cartons and corrugated packaging securely. Hot melt bonds instantly to recycled cardboard, handles high throughput at the packing station and is the cheapest sealing tape per meter. For online retailers and fulfillment providers, that makes it the standard – with or without a logo.

Warehousing and Logistics

In logistics centers, packing tape runs through hand dispensers with a brake, tabletop dispensers and automatic case sealers. Hot melt packing tape unwinds evenly, can be adjusted to the machine tension and keeps cartons shut even when they're stacked, transshipped and bumped on roller conveyors over and over.

Industry and Manufacturing

Outer packaging for components, bundling cables and profiles, fixing protective films, securing packing slips to the carton: hot melt provides a strong, flexible bond that shrugs off mechanical stress. For especially heavy packages or very rough surfaces, it's worth reaching for the reinforced Super-Melt packing tape.

Trades and Installation

Tool crates, spare parts cartons, deliveries to the job site: trade businesses use hot melt packing tape for sealing, for temporarily fixing films and insulation materials, and for bundling. Important for outdoors: standard hot melt is meant for dry, UV-protected applications – when it's exposed to wind and weather, reach for PVC tape.

Branding on the Carton

Every sealed carton is an advertising space the recipient is guaranteed to look at. Printed hot melt packing tape with your logo turns a plain brown box into a branded package – without having to stock printed cartons. How the printing works is covered in Chapter 8.

Real-world example

Packing Station in Online Retail

A shop shipping 300 packages a day uses around 2.6 m of tape per carton with an H-seal (top and bottom). That's about 12 rolls of 66 m per day – so a starter pack of 36 rolls lasts for three shipping days. You'll find the math in the practical tips.

Chapter 5 · In Practice

Using Hot Melt Packing Tape Right: 7 Practical Tips

Most complaints about "packing tape that doesn't stick" have nothing to do with the tape itself, but with dust, cold or too much tension during unwinding. With these seven points, you'll get the full adhesive strength out of every roll.

01

Clean, Dry Surface

Dust, grease and moisture are the most common causes of poor adhesion. Wipe down cartons that have been sitting open in the warehouse for a long time before sealing them. Very dusty recycled cartons with a high fiber content call for a higher coat weight – that's what the reinforced Super-Melt is for.

02

Temperature in the Green Zone

Tape and carton should be processed at +10 to +40 °C. Let cold goods from the outdoor warehouse acclimate first, and don't leave rolls in the van overnight. Below +5 °C, the hot melt gets too stiff to wet out the surface.

03

Press Down Firmly – That's Half the Seal

Pressure-sensitive adhesive needs pressure to flow into the fibers. Run the pressure roller of the dispenser or the heel of your hand firmly along the entire length once. Avoid bubbles and wrinkles: every wrinkle is a spot where the tape will lift first later on.

04

H-Seal for Heavy Cartons

Seal the center seam and additionally tape both end seams, each with 5 to 8 cm of overhang at the edges. The tape forms an "H" and keeps the flaps from bulging open. For cartons over 15 kg, seal the bottom as an H as well.

Center seam plus both end seams: this way even a heavy carton stays securely closed.

05

Unwind Properly: Tension Isn't Adhesion

160 % elongation at break doesn't mean you should stretch the tape. Stretched tape contracts after application and lifts at the ends (flagging). Set hand dispensers with a brake and case sealers so that the tape lies taut, but without being stretched.

06

Store It Like Food: Cool, Dry, Dark

15 to 25 °C, below 65 % humidity, no direct sunlight, in the original packaging. Store rolls upright or lying flat on the core so the edges don't get damaged. Use the oldest rolls first (FIFO) and plan your stock so that a batch is used up within 12 months – the performance warranty per data sheet is 6 months from delivery.

07

Calculate Your Needs Correctly

Rule of thumb: for each strip of tape you need the carton length (or width) plus 10 cm of overhang. From that you get how many cartons you can seal with one 66 m roll – the table below works it out for a typical shipping carton.

Chapter 6 · Comparison

Hot Melt vs. Acrylic vs. Natural Rubber vs. Paper: Which Packing Tape When?

Packing tapes differ less in their film than in their adhesive. Four adhesive systems dominate the market – and each has an application in which it beats the others.

The most important figure for a head-to-head comparison is tack, the initial tackiness. In the rolling ball test, a steel ball rolls across the adhesive layer; the shorter the distance, the tackier the adhesive. Our hot melt comes in at 7 cm, the natural rubber adhesive on our PVC tape at 2 cm. In return, hot melt achieves a very high peel strength of 4.9 N/cm on steel – the ultimate adhesion once the adhesive has had time to wet out the surface. Two adhesives, two strengths: natural rubber grabs instantly, even in the cold; hot melt holds permanently on cardboard and costs less.

Acrylic adhesives play a third role: they're the least tacky at the moment of application, build up their adhesion over hours and in return are the most aging- and UV-resistant. And paper packing tape brings a fourth factor into play that no film tape can offer: it gets recycled together with the carton.

Chapter 7 · Sustainability

How Eco-Friendly Is Hot Melt Packing Tape?

Honest answer: it's a plastic tape – but among film tapes, it's the one with the slimmer footprint. What speaks for it, what speaks against it, and which rules have applied since 2026.

Solvent-Free: The Biggest Plus

Hot melt is melted and coated as 100 percent solids. There are no solvents evaporating during production (no VOC emissions) and no water that has to be removed in energy-hungry drying tunnels. Nothing smells while you're packing, and according to the data sheet, the tape contains no hazardous or harmful substances.

What Happens to the Tape in Paper Recycling?

You don't have to peel packing tape off the carton before disposing of it. In the paper mill's pulper, the corrugated cardboard breaks down into fibers, while the PP film together with its adhesive is screened out as so-called rejects and usually sent to energy recovery. So the hot melt tape doesn't disrupt the recycling process – but it doesn't become new material itself, either. If you want a genuine material loop, go with paper packing tape with natural rubber, which is recycled together with the carton.

Produced solvent-free, unproblematic in paper recycling – and with paper tape as the alternative for a genuine material loop.
New since 2026

PPWR: The EU Packaging Regulation

Regulation (EU) 2025/40 on packaging and packaging waste (PPWR) has applied directly in all EU member states since August 12, 2026. Packing tape counts as a packaging component under it. For you as a retailer, this means: your supplier must comply with the substance requirements – such as the combined limit of 100 mg/kg for lead, cadmium, mercury and hexavalent chromium – and ensure the traceability of every batch. From 2030, recyclability requirements will be added on top.

Compliance

EU Declarations of Conformity at Tapemonster

EU declarations of conformity under Art. 39 PPWR are available for our PP packing tapes: No. PPWR-2026-S03 for PP Hot-Melt (loud unwind) and No. PPWR-2026-S04 for PP Super Hot-Melt (quiet unwind). They cover the substance requirements of Art. 5 to 12, including REACH/SVHC, POPs and PFAS. You can download the declaration for PP Hot-Melt (PDF) directly – important for micro-enterprises shipping printed tape under their own brand.

Alternative

Paper Packing Tape for Mono-Material

If your packaging is supposed to be made entirely of paper, printed paper packing tape with natural rubber adhesive is the logical choice: paper backing, quiet unwind, recyclable with the carton and with a matte, premium print finish. For heavy packages, there's the reinforced version.

How to pack more sustainably with hot melt
  • Once done right instead of three times over: Pressed down cleanly, one strip holds – every second strip is material nobody needs.
  • H-seal only where it's necessary: Light cartons up to about 10 kg usually need only the center seam.
  • Right carton size: Less air in the package means less void fill, a smaller carton and a shorter strip of tape.
  • 48 mm instead of 75 mm: For standard cartons, the narrow width is perfectly sufficient; wider tape doesn't deliver proportionally more holding power on corrugated cardboard.
  • Use up rolls, keep an eye on the batch: FIFO in the warehouse keeps over-aged rolls from having to be thrown out.
Chapter 8 · Logo Printing

Printing Hot Melt Packing Tape: How Your Logo Gets Onto PP Tape

The smooth, corona-treated PP film is the most forgiving substrate flexo printing knows. That's why hot melt packing tape is the most-ordered material for packing tape with a logo – and the cheapest.

Printing is done by flexo printing: your design sits in relief on a flexible printing plate, the cliché, which is inked and pressed against the moving film web. The flexo printing plate is made once and kept on file for reorders – so the printing plate costs apply to the first order only. One to three ink colors are possible per design, which we match to Pantone. For the substrate you can choose white, brown or clear film – or, on request, a through-dyed custom color as the background.

Technically, printing doesn't change the adhesive properties at all: coat weight, adhesion and elongation remain those of the unprinted tape. What changes is the effect – a brown package with logo tape is perceived as a branded package before it's even opened.

Print file tip

Supply your logo as a vector file (PDF, AI, EPS or SVG), convert fonts to outlines and specify colors as Pantone values. Everything else is in our print file guide. Before printing, our free data check reviews every file – we only print after your approval.

Chapter 9 · Glossary

Technical Terms Around Hot Melt Packing Tape – Explained Briefly

The most important terms from data sheets, quotes and this guide. You'll find even more packing tape vocabulary in the Tapemonster Lexicon.

Hot melt (hot melt adhesive)
An adhesive that is melted hot and applied without solvents or water. On packing tape, it stays permanently pressure-sensitive after cooling.
Pressure sensitive adhesive (PSA)
An adhesive that bonds simply by being pressed down – without heat, water or curing time. All packing tapes work with pressure sensitive adhesives.
PP film (biaxially oriented)
Polypropylene film that has been stretched lengthwise and crosswise – which makes it thin, tear-resistant and dimensionally stable. The standard backing material for PP packing tape; other suppliers call the same film BOPP.
Tack (initial tackiness)
How quickly and strongly an adhesive grabs on first contact. Measured, for example, in the rolling ball test: the shorter the distance the ball rolls, the higher the tack.
Peel adhesion (to steel)
The force needed to peel an applied tape off at a 180° angle, given in N/cm (tested per ISO 29862). A measure of ultimate adhesion.
Coat weight (g/m²)
The amount of adhesive per square meter of film. 17 g/m² corresponds to a layer thickness of around 20 µm. Higher coat weight = more adhesion on rough surfaces.
Synthetic rubber (SIS/SBS)
Styrene block copolymers, the base polymer of hot melt pressure sensitive adhesives. Provides elasticity and cohesion.
Tackifier
Tackifying resins that make the rubber tacky in the first place and control how it wets out the surface.
Cohesion and adhesion
Adhesion is the bond between adhesive and substrate; cohesion is the internal strength of the adhesive layer. A good tape needs both in balance.
Natural rubber adhesive
Solvent-based adhesive made from natural rubber with very high tack and good cold performance. At Tapemonster, used on PVC and paper packing tape.
Acrylic dispersion
Water-based adhesive made from acrylic esters. UV- and aging-resistant, but with lower tack and slower adhesion build-up.
Release coating
Wafer-thin release layer on the back of the film that makes unwinding possible. Its formulation helps determine whether a tape unwinds loudly or quietly.
Quiet unwind
Tape versions with an adapted film and release layer in which the typical ripping noise during unwinding is largely eliminated – such as our Super-Melt.
Elongation at break
The percentage the tape stretches before it tears (tested per ISO 29864). Our PP Hot-Melt reaches 160 %.
Flexo printing plate (cliché)
The flexible printing plate in flexo printing on which the design sits in relief. Made once and kept on file for reorders.

Frequently Asked Questions About Hot Melt Packing Tape

The questions that reach us most often by phone and email – answered briefly and without beating around the bush.

What does "hot melt" mean in packing tape?

Hot melt refers to the adhesive, not the film: a hot melt adhesive based on synthetic rubber that is applied to the PP film in liquid form at around 150 to 180 °C and solidifies into a permanently pressure-sensitive layer as it cools. That's why hot melt packing tape bonds simply by being pressed down – without heat, water or drying time.

What's the difference between hot melt and acrylic packing tape?

Hot melt packing tape bonds immediately after being pressed down and wets out rough surfaces like recycled cardboard very well; in return, it's more sensitive to heat and UV. Acrylic packing tape has less tack at application, builds up its ultimate adhesion over about 24 hours, but is more aging- and UV-resistant and tolerates temperatures up to around 80 °C. For day-to-day shipping, hot melt is the more efficient and cheaper choice; for long-term storage and outdoor applications, acrylic or natural rubber.

What temperatures can hot melt packing tape handle?

As guideline values: application at +10 to +40 °C (not below +5 °C), service after sealing at about −20 to +60 °C. Constant exposure above 50 to 60 °C – for example in an attic in summer or in a truck parked in the sun – softens the adhesive and weakens the bond. For such cases, we recommend PVC tape with natural rubber or acrylic tape.

Can I use hot melt packing tape outdoors?

Standard hot melt is meant for dry, UV-protected indoor applications. Constant sunlight, rain and large temperature swings age the rubber adhesive. For outdoor use, PVC packing tape with natural rubber is the better choice – it's more weather-resistant and UV-resistant.

Why does hot melt packing tape unwind so loudly – and are there quiet versions?

The noise is created when the adhesive separates abruptly from the release layer of the layer underneath during unwinding. A thicker, stiffer film and an adapted release coating dampen this effect. Our Super-Melt packing tape uses a 28 µm film with a total thickness of 50 µm and unwinds quietly – ideal for packing stations in the office or retail store.

How long does hot melt packing tape last and how do I store it properly?

According to the data sheet, the tape's performance is warranted for 6 months from delivery; with proper storage, adhesive strength lasts considerably longer in practice. Store the rolls at 15 to 25 °C, below 65 % humidity, out of direct sunlight and in the original packaging, upright or lying flat on the core. Use older rolls first (FIFO) and plan your stock so that you use it up within 12 months.

Why isn't my packing tape sticking properly?

The most common causes are dusty, damp or greasy carton surfaces, application below +5 °C, tape applied under too much tension (it pulls back and lifts at the ends) or rolls stored too warm. Wipe down the surface, make sure it's at room temperature, apply the tape without stretching it and press it down firmly. On very rough recycled cardboard, switching to the reinforced Super-Melt packing tape helps.

What's the difference between hot melt and Super-Melt packing tape?

Super-Melt is our reinforced version of PP packing tape: 28 µm instead of 25 µm backing film, 50 µm instead of 45 µm total thickness and a reinforced hot melt formulation. It stands up better to heavy cartons, rough surfaces and industrial use – and it unwinds quietly.

Can hot melt packing tape be custom printed?

Yes. PP packing tape with hot melt adhesive is the most-ordered material for packing tape with a logo: the corona-treated PP film is flexo-printed with one to three Pantone colors on white, brown or clear film. At Tapemonster from 36 rolls, with delivery usually 18 to 22 business days after print approval.

Do I have to remove hot melt packing tape from the carton before recycling?

No. In the paper mill's pulper, the carton breaks down into fibers while the PP film together with its adhesive is screened out as rejects and sent to energy recovery. The tape doesn't disrupt paper recycling, but it isn't recycled itself, either. If you want a complete material loop, use paper packing tape with natural rubber, which is recycled together with the carton.

Is hot melt packing tape food safe?

Our packing tapes are not intended for direct contact with food. For sealing the outer carton of a food shipment, they're not an issue as long as the tape doesn't touch the goods. According to the data sheet, the tape contains no hazardous substances and is REACH-compliant.

How many cartons can I seal with one roll of hot melt packing tape?

For each strip of tape you need the carton length plus around 10 cm of overhang. For a 400 × 300 × 200 mm shipping carton, one 66 m roll is enough for about 66 cartons with a simple seal top and bottom, about 36 cartons with an H-seal on top, or about 25 cartons with an H-seal top and bottom. A starter pack of 36 rolls therefore covers around 900 to 2,400 cartons.

Does hot melt packing tape fit every tape dispenser?

Every common one: the rolls have the standard 76 mm (3") core and are 48 or 50 mm wide. Hand dispensers, tabletop dispensers and case sealers for 48/50 mm tape take them without any adjustment. A hand dispenser with a brake helps apply the tape evenly and without stretching.
