TPU Hot Melt Adhesive Film for Garment Accessories

Bond elastic waistbands, labels, trims and no-sew panels with a solvent-free adhesive layer that stays soft, stretches with the fabric, and survives the wash – supplied to your thickness, activation temperature and width by Tengyang.

tpu hot melt adhesive film is a thermoplastic polyurethane bonding layer, non-tacky at room temperature, that activates under heat and pressure to form a soft, elastic, wash-durable bond between fabrics and trims – with no stitching and no solvent glue. For garment accessories it’s chosen where the bond must flex, stay invisible, and pass laundry testing.

Bonding Garment Accessories Without Stitching or Solvent Glue

Challenge

Every garment-accessory line eventually hits the same problem: stitching punctures elastic panels and leaves a hard 2-3mm seam, while solvent-based glues release VOCs and cure unevenly.

Dry Solution

A tpu hot melt adhesive film removes both failures because it replaces liquid chemistry with a dry, pre-measured adhesive layer. You place the hot-melt adhesive film between two materials, activate it with a heat press or lamination roller at a set temperature, and let it cool into a flexible bond – no drying time, no stitch line, no mess.

Chemistry

Chemically, TPU is an advanced adhesive material: a thermoplastic copolymer of a diisocyanate and a polyol (see patent WO2020136106A1). That structure is the root cause of its range – the same tpu material can be engineered to run as a very soft, low-temperature grade or a firm, high-wash grade with strong bonding and water resistance.

Performance

Unlike traditional hot melt glue, which sets hard, TPU stays elastic, which is why it has become the practical adhesive solution for waistbands, bra components, labels, appliqué badges and reflective trims that must move with the body.

Tengyang TPU Films & the Garment-Trim Grade Playbook

A hidden risk in sourcing hot melt film is buying by thickness or price and discovering the grade is wrong on the line. A bonded waistband, a printed care label and a reflective strip don’t share the same heat tolerance or wash demand, so one universal film always fails somewhere. Tengyang produces tpu hot melt adhesive film and web in single- and double-sided adhesive constructions, with or without release paper, engineered to the job rather than sold as a single spec. The formulation freedom behind this – trading melting point against bonding strength – is documented in patent CN104263259A, a low-melting-point, high-adhesive-strength tpu film.

Why grade matching is decided in-house

Tengyang has our own casting, blown-film, granulating, melt-blown web, slitting, and rewinding production lines. And we’ve the benefit of 15+ years experience selecting hot-melt materials. It’s the in-house chain that gives us the structure to tailor the melt point, weight, substrate, and hand of the two fabric partners, rather than try to mold your application into the standard specifications of an off-the-shelf roll – a capability OEM buyers need for consistency.

Activation Windows & Substrate Heat Ceilings

tpu film – low or high temperature grade? Neither is the default answer. Low-temperature grades safeguard sensitive finishes; high-temperature grades increase resistance to washing and dry cleaning. Make the decision by what’s least hardy – the weaker of the two substrate materials. Don’t pick based on the hardest weld you can achieve.

Everyone is led to believe that weak bond = bad film. However experience in the field shows this isn’t always the case: Bubbling or delamination after bonding is often a result of process or material errors (such as trapped moisture, incorrect temperatures, insufficient dwell and pressure) as opposed to being an adhesive failure, this is the reality of the majority of “poor adhesion” problems and it’s also the reason the temperature ladder that follows is only one half of the issue, the other is the temperature limit of the substrate.

Can scorch heat-sensitive substrates

Given that hot air, high-frequency and ultrasonic sealing, roller lamination, heat press and other tpu hot melt methods all exist for films, a given film could potentially run on disparate pieces of equipment; as can be seen in this example of multi-method activation of textile bonding from Covestro. The path to a low-melt film that nonetheless offers excellent bond strength and chemical resistance (a non-reactive hot melt TPU derived from an excess of polyol) is described in patent US20170058163A1. What matters on your line is matching activation temperature, dwell time and pressure to the substrate, which is where a sample trial replaces guesswork. Because the film keeps good resistance and good resistance to chemicals across these hot melt applications, confirming the bonding window against your substrate is the right call, and Tengyang will run a sample to set it.

“On heat-sensitive trims we start a full 20–30°C below the substrate’s damage point and win the bond back with dwell time and pressure, not more heat. Most weak-bond complaints we see are under-pressed, not under-heated.”

TPU vs EVA, PES, PA and PO Hot Melt Films

The issue most buyers struggle with is performance versus price – EVA or PO can be supplied more cheaply than TPU and frankly you only buy them if the requirement to stretch and survive laundering is more than you can afford from a cheaper hot melt – otherwise you compromise too much on the strength of a genuine adhesive film. This chart compares performance typical in industry — the way 3M and HB Fuller draw distinctions between the film family of product as well as way the convertor selects grade to match function, not lowest cost.

Film Typical melt point Elasticity Wash resistance Hand feel Best-fit use
TPU ~65–180°C (wide) High High (esp. hi-temp) Soft, elastic Elastic apparel, waterproof, reflective
PES (polyester) ~120–150°C Low High / dry-clean Firm Polyester fabric, labels, shape stability
PA (polyamide) ~110–170°C Low–medium High + dry-clean Firm Embroidery badges, technical textiles
EVA ~70–110°C (low) Medium Low Soft Cost-sensitive, low-wash bonding
PO (polyolefin) ~90–130°C Medium Medium/washable Medium Economical washable components

The TPU adhesive film also goes well beyond garments, as that formula flexibility allows it to be formulated into foams or composite constructions (patent CN103571364A), or even into zigzag and medical applications. For an economical low-wash trim, EVA or PO works best. For something that stretches and is subject to laundering, a TPU is well-justified. Tengyang sells all five film families, so if a more affordable film can do the job, the company recommends it. TPU adhesive film uses are not always the premium call: for a low-wash trim a cheaper film is engineered to the job, and that is the honest recommendation.

TPU Film Formula Flexibility and Application

Garment Accessory Applications: Elastic, Trims, Labels & Reflective

What does tpu film replace? Wherever stitches are slow or liquid glues are messy. tpu film, as a fabric interlayer, runs the length of the garment and apparel-accessories value chain and can even expand into the broader textile sector where an effective, no-sew, flexible attachment outperforms other methods. The following chart describes a number of production scenarios, and the ideal tpu film grade for each.

In fact, tpu film works so well it can integrate into and simplify many adjacent lines, including footwear uppers/soles, outdoor gear, automotive textiles, and home decor, enabling converters that produce garment accessories to source most films from one manufacturer. Within the tpu film industry, your combination of fabric-to-fabric pairing and application process determines the correct film starting grade, which the Playbook guides you toward and sample testing verifies. Tengyang supplies these grades from its own production lines, which is the reason a converter can consolidate textile industry sourcing across garments, footwear and automotive interiors; as a tpu hot melt adhesive film for fabric, the grade is engineered to your pair because the fabric leads the decision, which is the right call.

TPU Film Garment Accessory Applications
  • Waistbands with elastic and stitch-free panels

    A mid-temp elastic-specific grade can fuse panels with sufficient elasticity and recoverability without creating a hard seam line for underwear or active wear production (approx. 120°C, 0.10mm).

  • Bra cup and moulded lingerie panels

    The low-and-mid grade films attach well below temperatures that would flatten foam or imprint the garment fabric surface (approx. 110°C).

  • Care label and woven labels

    This very thin (0.06mm) low temp film attaches and converts plain woven or printed labels into sew-free heat applied trim. Suitable for mass-production OEM apparel manufacturers.

  • Reflective trim and heat transfer graphics

    Clear low-temp film creates heat-applied trims such as reflective stripes and can turn an embroidered patch into an iron-on accessory. Reflective heat transfer lamination Constructions are detailed in patent CN202781974U.

  • Nylon and coated technical fabric

    Bonding to nylon, a difficult material for any glue, is reliably handled by a high tack grade of our TPU film (approx. 150°C).

Cleaner and Faster Than Solvent Glue or Stitching

Cost mistake with hot melt film is in the per unit cost not in the true cost of usage. Our dry, pre-measured sheet form eliminates the costly and variable expenses of buying, storing and handling of liquid glues and stitching for most trim applications. By improving production efficiency without the need to add staff, total cost savings are substantial, although hard to put an exact number on. Here’s why our costs differ.

Advanced Hot Melt Film Application Material

Total-cost factors a hot melt film changes

Solvents & VOC’s

Purchasing and storing large volumes of solvents for glue are eliminated. Environmental compliance and worker safety controls related to workplace VOCs are bypassed as there are no solvent emissions when the dry film is heated and activated.

Labor & Steps

Simply place and press, versus spreading, drying time, and, for many trim applications, a secondary stitch application.

Waste & Rework

Eliminates many common liquid glue rejects, like uneven distribution, while improving application quality and speed. Most rework failures for dry films are attributable to inadequate application temperature/pressure, not the film itself.

Clean-room and appearance

no glue mess or needle holes protects the finished-garment look and the wearer’s comfort.

In practice, an OEM apparel producer that switches a trim from sewing or solvent glue to tpu film trades a higher material line-item for lower labour, lower reject and lower compliance overhead. Where those numbers land depends on your volume and process, which is why we scope them per application. To see the drivers mapped to your line, request a factors worksheet. Because Tengyang runs its own production lines, the cost of a switch is engineered to your process rather than guessed; unlike a stock roll, the grade is matched to your line.

Compliance and Wash Testing for Textile Bonding

The trust gap for international buyers is real: “eco-friendly” is no longer accepted as a claim, and a supplier that cannot name the standard, class and document loses the audit. tpu hot melt film is solvent-free by construction, and Tengyang can supply grades tested and documented to the standards your market requires under quality-managed, ISO 9001-aligned production. The scopes below are not interchangeable, so precision matters:

ISO 6330

Textile wash-test method — the reference for wash durability

OEKO-TEX® 100

Product-class certification; Class 1 = direct skin contact

REACH / SVHC

Substance-level EU obligation

PFAS-free

Increasingly required by textile brands

Wash durability is measured, not asserted: the recognised method is ISO 6330 domestic washing and drying, and specialist textile-bonding films are engineered to hold peel strength through 30 or more ISO 6330 cycles for high-wash apparel – an industry-typical benchmark, to be confirmed against your grade by sample testing. OEKO-TEX STANDARD 100 (per oeko-tex.com) is product- and component-class specific: Class 1 covers items in direct skin contact, whereas REACH/SVHC (per ECHA) is a substance-level obligation, so a supplier can meet one and still owe documentation on the other. Tengyang provides certified third-party test reports for supplied grades and prepares OEKO-TEX / REACH-aligned documentation on request, rather than claiming a blanket certificate an auditor would question.

Tengyang TPU Film OEM Production and Procurement

Procurement Guide: Custom Specs, Samples and OEM Supply

The procurement risk is a vague RFQ that produces a vague quote and a wrong film. The fastest route to a usable quotation is to tell us the application, not just a thickness. Tengyang supplies to OEM specification – custom thickness, width, melting point, colour and application-specific formulation – as an adhesive solution engineered around your process, under quality-managed production consistent with ISO 9001 practice and backed by 15+ years in hot-melt materials. For teams researching where to buy TPU adhesive film in production volumes, pricing is driven by the variables below rather than a single list price:

Send this before asking for a quote

  • The two substrate materials to be bonded (for example elastic fabric plus nylon)
  • Finished-product use and wash or dry-clean requirement
  • Activation equipment: heat press, roller, hot air, high-frequency or ultrasonic, with your temperature, time and pressure window
  • Target thickness or hand feel, required roll width and length
  • Release paper, film or carrier-free preference
  • Colour, transparency or surface need
  • Trial quantity and estimated bulk volume

For new bonding structures we recommend a sample trial before bulk commitment – it settles thickness, carrier, temperature and pressure with your real materials and removes the largest source of production surprise. Firm price, MOQ and lead time follow the specification: contact Tengyang for a quotation based on your application parameters. Confirming the grade against your real materials first is the right call before you commit to a bulk run.

FAQ: TPU Hot Melt Adhesive Film for Garments

01

What is the difference between TPU hot melt adhesive film and TPU film? / How do I choose high-temperature vs low-temperature film?

Choose by the more heat-sensitive of your two substrates. Reflective trims, printed labels and coated or elastic fabrics usually need a low-temperature grade (~65–110°C); sportswear and high-wash items justify a high-temperature grade (~150–180°C) for stronger wash resistance and excellent adhesion.
02

Which TPU hot melt adhesive film has good washability?

Higher-temperature TPU grades give the best wash and dry-clean resistance. For apparel, look for grades formulated to hold bonding strength through 30+ ISO 6330 wash cycles, and validate on your own fabric before bulk ordering.
03

Is it environmentally friendly and non-toxic?

TPU hot melt film bonds without solvents, so there are no VOCs during application, which makes it an environmentally friendly material for modern production. For skin-contact garments, ask for a grade supplied to OEKO-TEX STANDARD 100 and confirm REACH/SVHC and PFAS-free status for your market.
04

Why does the bond bubble, foam or peel after pressing?

Usually the film isn’t the cause. Bubbling and delamination most often come from trapped moisture, the wrong activation temperature, or too little dwell time and pressure. Dry the substrates, confirm the temperature window and increase press time or pressure before changing film.
05

Will it melt or come apart in summer or in the wash?

A correctly matched grade won’t. The activation temperature is well above normal wear and storage conditions, and high-temperature grades are built for repeated laundry. Problems point to an under-specified grade for the end use, which the grade guide above is meant to prevent.
06

Can you supply custom thickness, width and colour?

Yes. Tengyang supplies OEM: custom thickness, width, melting point, colour and application-specific formulation, in single- or double-sided constructions with paper, film or carrier-free release.
07

Do you provide samples before a bulk order?

Yes. Send your two substrates and process details and we prepare a sample direction for trial bonding. Sample validation is the recommended step before any bulk purchase.
