Hot Melt Adhesive Web, TPU, EVA, PA, PES & PO Bonding Webs for Industrial Lamination
Bond fabric, foam, leather and technical textiles with a clean, solvent free web – matched to your melt point, wash requirement and production line.
A hot melt adhesive web is a non-woven fabric-like sheet of thermoplastic adhesive. It’s designed to be melted and pressed between two substrates so as to glue them together as the web cool. We at Tengyang manufacture these webs in five different families of polymer (TPU, EVA, PA (polyamide), PES (polyester) and PO (polyolefin) so that the melt point, elasticity and wash resistance can be matched to your part instead of fitting your process to a standard glue. The following is written with the engineer who needs the material in mind, the buyer who want a reliable supply and the production manager who’s frustrated at having to work to the constraints of a solvent glue.

From Solvent Glue to Clean Web Bonding, And How a Web Differs From a Film
Here's a rule of thumb worth fighting against before you specify: solvent adhesives aren't always the more durable of options. For many years solvent systems were believed to last longer, but now hot melt webs are providing a bond that matches or exceeds it, on textile bonds without the accompanying drying tunnel and emissions. The honest version: a modern hot melt web matches or beats solvent durability on textile work, so that older rule is not industry truth. Once you realize how much more streamlined a lamination line can be, that single change impacts the costs dramatically.
The pain
Solvent-based bonding needs the glue laid down wet, then driven off in a heated drying tunnel. Fibers can be left with gaps or pinholes, VOCs (volatile organic compounds) are released which affect insurance and regulatory costs and more often than not every meter has to be pre-dried before the job can even begin.
Our solution
Our web is 100% solid, so carries no solvent and no water. It activates solely from heat and pressure and reaches strength as it cools, without causing emissions at the bonding step.
The cause:
Liquid adhesives carry a solvent or water phase that must physically leave the bond line before the bond is strong enough to hold. The simple fact that the polymer can be melted together is irrelevant until this water or solvent has left the system.
The proof:
Solvent free web and film lamination runs at far higher line speeds than solvent systems as there's no need to pause and await the drying tunnel, the only other limiting factor being heat transfer rate and time.
Where a solvent line is designed around a drying tunnel, a web line is designed for bonding with only heat and pressure-and there’s no bones about it: You must match the melt point (which range from 70C to 150C, roughly, across the families) to your fabric, instead of letting a wet glue soak into the substrate where it can leave voids. And since that bond is 100% solid, wash durability is validated per ISO 6330 methods rather than assumed. Every one of our web products are manufactured in house on our own meltblown and coating lines and benefit from years of formulation control; grades are therefore consistently behaved unlike traded commodity roll stock.
Web vs film, a practical distinction
Buyers often juxtapose the web against the film and the difference is structural. Web is an open, non-woven mesh of thermoplastic, whereas film is a solid sheet. The open nature of a web allows it to drape and conform like a fabric and it adds less stiffness to sensitive materials, whereas a solid film create a full breadth seal.
Engineering note, breathability is a process outcome, not a given
The porous geometry of a web support air permeability, but the breathability of the finished laminate isn't guaranteed by the web alone. Adhesive add-on weight, melt flow, pressing pressure and dwell time all decide whether the pores stay open or close under lamination. For a breathable result, specify the areal weight and process window together, and confirm on a sample of your own fabric.
Since Tengyang offers both webs and films, we can move you into the film form of your same polymer when your part needs full area sealing instead of a light, breathable attachment - no supplier change required.

Application-specific formulation on request
All of this can be translated into an RFQ - let's know your material, heat press range, substrate thickness/weight/width and whether release paper is needed - and we’ll recommend a specific grade instead of shipping you a generic roll.
Whether you are using hot melt adhesive on woven textiles, foam, leather or plastics, both web and film forms are designed to hold many different materials across a broad temperature range — from low-melt EVA for heat-sensitive parts to PA and PES grades with high temperature and excellent chemical resistance. Each grade is tailor-made to your application requirements rather than pulled from a fixed catalog, so one supplier covers substrates that would otherwise need several adhesive chemistries.
We differ not by what we put in the roll, but by how we match it. Unlike a commodity provider that ships a single weight and expects you to find the application window, Tengyang engineers the product specifically to your substrates: the thicknesses, areal weights and melt points of the webs on our own meltblown, casting, coating and slitting lines are controlled in production-not improvised. A wrongly selected grade is the most expensive mistake a lamination facility can make, so we'll confirm the application window on a bonded sample prior to production.

Technical properties & customization
All grades are thermoplastic hot-melt web adhesives, meaning they're free of solvent and they don't cure chemically - instead, they melt and bond upon heating and solidify upon cooling to provide strong bonds in seconds. The precise curing time, melt viscosity and activation window are formulation dependent, so each web is a raw material rather than a one size fit all solution that has been custom-tailored for specific applications. As such, a custom formulated TPU hot melt adhesive web for stretch, PA hot melt adhesive or polyamide web for wash/heat resistance, or PES web for washable technical applications with any desired melt point, color, width, thickness or chemical resistance is no different from ordering a standard grade; in fact, our webs are frequently used in laminating electronic components, bonding foam, attaching to board materials and more, and the application areas far transcend garment use for lasting bonds with excellent adhesion and proven temperature resistance.
The Bonding Web Selection Compass, Melt Point, Wash Resistance & Elasticity Compared
Choosing a web is all about trade-offs. Starting from a web that melts at low temperature may not be the best route. Polyethylene melts at 160-190C and EVA and low-temperature TPU activate at 70C, so a web that melts at 70-80C may not necessarily be the best choice. To determine this, think about a web's melt point, its wash durability, and its stretch characteristics; then find the web with the best combination of all. The following web Compass shows five families of web technologies and how they relate to the decisions we need to make when choosing a web.
| Material | Melt point | Bonding temp | Elasticity | Wash resistance | Dry-clean | Key strength | Typical application |
|---|---|---|---|---|---|---|---|
| EVA | ~70°C | Low tier | Moderate | Fair | Fair | Lowest activation, economical | General fabric, packaging, heat-sensitive parts |
| TPU (low) | ~70°C | ~100°C | High | Good | Good | Stretch + waterproof | Elastic seams, stretch fabric, outdoor gear |
| TPU (medium) | ~110°C | 130–150°C | High | Good | Good | Elastic + higher heat | Footwear, laminated membranes |
| PO (polyolefin) | 95–105°C | 115–130°C | Low–moderate | Good | Good | Bonds PP/PE, solvent-resistant | Polyolefin plastics, technical films |
| PES (polyester) | ~120°C | 125–135°C | Low | Excellent | Excellent | High-temp + washable | Apparel, electronics, metal-to-fabric |
| PA (polyamide) | ~150°C | High tier | Low–moderate | Excellent | Excellent | Highest heat + strongest bond | Collars, badges, technical textiles, bonded garment seams |
| PE (reference) | — | 160–190°C | Low | Good | Poor | Low cost | Basic fusible interlining |
Keep in mind that these "typical" ranges are reported by many adhesives sources and references but they aren't set in stone. Melt points differ with grade, formulations and additives: EVA change behaviour depending on vinyl-acetate content, and copolymer blends will move the activation window. Ultimately it's up to the datasheet of each individual grade to settle the debate, so take this web Compass as a guide and always verify on a bonded sample of your own substrate.
Reading the Compass by decision
For products that will be laundered or dry-cleaned such as collars, uniforms or technical gear, high adhesion PA and PES are the choices. Copolyamide webs offer very high specific adhesion and the highest resistance to wash and dry-clean, a trait documented in USPTO patent [US 4,217,256] for polyamide adhesives used for fabrics and further refined in copolyamide hot-melt formulations in [US 3,989,678]. For products that need to stretch such as sportswear, elasticated garments and stretch membranes, TPU adheres and moves with the fabric without cracking. For products that are sensitive to high heat such as delicate or art fabrics, EVA and low-temperature TPU at 70C ensure heat-sensitive material safety over a PA which can be processed at 150-160C.
While commodity rolls leave your selection up to trial and error, Tengyang quantifies it. As the real application is a function of your fabric not your datasheet, we bond candidate web grades to your substrate in our lab, then report the result of your actual line temp press (from ~70°C to ~150°C). It’s the real process choice- not always highest melt web, but the grade that withstands your wash and won't burst open on your press. Best hot melt web means the one that adheres well to your fabric and wash process, not the strongest one on paper. Copolyamide chemistry (documented in USPTO US3989678) provides your wash resistance while TPU gives up a bit of heat for stretch in your bond.

Engineering note, why bonds fail, and the moisture trap
Usually it isn't the web that let us down, but the heat range. If it's too low it won't fully coalesce with the fibres: too high and it will over-penetrate the fabric and lose the desirable hand or back through the fabric. PA has a third pitfall though. PA will absorb moisture from the air and that moist air will expand during pressing, creating foam and weakening the bond. Your best countermeasures here are dry storage of stock and a verified pressing range, plus a test on the fabric to be bonded before production begins.
"We do not hand a customer a datasheet and call it a spec. Melt point and wash resistance shift with the grade and the fabric, so we run a bonded sample on the customer's own substrate and pressing conditions before we lock a formulation - that trial is where the real window gets set." — Tengyang Application Engineering Team, Shanghai Tengyang New Materials
With or Without Release Paper, Choosing the Right Web Format
The only quality distinction between bare web (no substrate) and web on release paper is how it reaches the substrate- a handling decision. Bare web offers lower cost and higher through put in automated, web-first processes where web goes between two pieces of fabric. Web on release paper is easiest for manual handling- in appliqué or positioning smaller pieces where placement accuracy is key. We stock and photograph both types of rolls from our production, so you can identify the exact roll you'll be ordering.
| Format | Best for | Handling | Trade-off |
|---|---|---|---|
| Without release paper (bare web) |
Automated / continuous lamination lines | Placed directly between substrates | Harder to position small shapes by hand |
| With release paper | Badges, appliqué, precise manual placement | Cut, peel and register the shape, then bond | Added carrier cost; extra peel step |
Although format might appear a minor consideration, it has significant implications on production efficiency and costs; the misapplication of bare web on a manual line or release paper on automated equipment could lead to late discovery of errors as scrap weeks down the line. We therefore subject this selection to careful testing rather than arbitrary choices. We both convert and slit these formats in house within the same range of thicknesses (0.01-0.30 mm), empowering you to validate the ideal option on your own line with proven bond durability against ISO 6330 standards before committing to the entire production run. Unlike single-format suppliers, we ensure our web formats adapt to your production process, not the other way around.

Buyer advisory
Ensure that your selected web format is aligned with your specific assembly method: roll-to-roll automated production lines benefits from the time savings of bare web which eliminate an unwrapping and disposal step, whereas in die cutting and manual placement of smaller parts, release paper compensates for scrap loss with increased precision. In case of any doubts, take advantage of our sampling cards to evaluate both format options in the very conditions of your production.
Application Results, Garment, Stitch-Free Underwear, Footwear, Reflective & Automotive
One hot melt web family covers wildly different jobs- lining a shirt collar, bonding stitch-free underwear seams, attaching reflective strips, or securing an interior trim panel in a car. In these scenarios, the essential factors determining the optimal web remain the polymer and the appropriate pressing temperature range, rather than a variation in the process itself. Search terms vary — some buyers ask for a hot melt adhesive film automotive interiors teams can specify, others for a web for footwear or textile — but it is one product family matched to the substrate.
The hot melt web, activated by the combined application of heat and pressure, effectively creates durable adhesive bonds across a broad spectrum of materials- including woven and knit textiles, foam, leather, and films- and even within complex composite structures common in footwear manufacturing and automotive assembly. Higher melt point grades are particularly suited for lamination processes requiring superior temperature resistance, effectively bridging the gap between light apparel and structural components with a single web product range that can be tailored to the specific substrate.
Because the same polymer family can be matched to the material to be bonded, one web line covers many laminating applications across various industries — shoe manufacturing, carton and box assembly, and even bonding electronic components onto plastics and other different substrates. Used for bonding this many different materials from one product family, it removes the cost of qualifying a fresh adhesive for every job.
| Industry | Where the web bonds | Typical family | Why it fits |
|---|---|---|---|
| Garment & interlining | Collars, cuffs, waistbands, badges | PA / PES | Survives repeated laundering and dry-clean |
| Stitch-free / bonded-seam underwear | Bonded seams replacing stitching | TPU / PA | Flat, flexible seam with wash durability |
| Sportswear & stretch | Elastic seams, hem bonding | TPU | Stretches and recovers with the fabric |
| Footwear | Insoles, toe caps, linings | TPU / PA | Fast bond, flexibility, heat resistance |
| Reflective & heat transfer | Reflective strip & transfer lamination | PES / TPU | Clean film-free bond, wash-durable |
| Automotive interiors | Trim, door panels, headliners | TPU / PES | Holds through cabin heat and humidity |
| Leather & upholstery | Lamination and edge bonding | PA / PO | Strong bond to leather, foam and boards |
No drying tunnel
Because a hot melt web is 100% solid, the bonding step needs only heat and pressure — removing the solvent drying stage, its VOC controls and its wait time from the line.

Told the truth the payback is a process payback not a headline number - no solvent to buy store or ventilate; a stronger bond than inconsistent wet; and a faster meter because there’s no drying required. If a particular payback is of concern we'll scope against your line, not quote a generic.
Running heat-and-pressure bonding instead of a solvent line is also the more environmentally friendly, sustainable choice: activated by heat alone, the web brings no harmful chemicals onto the floor and helps reduce energy spent on solvent drying, while still forming long-lasting, reliable bonds that survive the environmental conditions of a hot cabin or a repeated wash cycle.
Given the mode of failure on these jobs is a bond which will soften in a hot car or delaminate after washing, Tengyang engineers the grade to the environment - PA and PES for laundered items (wash durability assessed per [ISO 6330]) and TPU close to 110C for footwear and the automotive cabin above 80C. This grade discipline, applied across years of production and running on our coating and slitting lines, makes the difference between a bond which passes an audit and a bond which doesn’t - as a single grade web, which would fail on softness, is engineered for your part.
Certifications & Compliance
Documentation closes the trust gap between an overseas buyer assessing a new supplier versus a brand they already know. Third-party test reports and certificates are available for Tengyang adhesives and durability tested to the most appropriate recognised test methods; wash durability using ISO 6330 for washing procedures and AATCC test methods for laundering test protocols; as opposed to the pass/fail certification itself. The appropriate certificate is supplied for the specific grade ordered for inclusion within your own documentation file.

For the procurement engineer, undocumented certification is a compliance risk and not a statement of reliability. Buyer audits fail on missing paperwork and not on the strength of a bond and so Tengyang maintains third party test reports on file and provides a copy certificate including its standard number with every order. While some suppliers use logo shorthand for standards they do not support, Tengyang explicitly states only the standard which the grade actually meets - tested to ISO 6330 and AATCC wash procedures for apparel and auto parts and engineered for 150C+ if required.
Procurement Guide, Custom Thickness, Width, Melt Point, Color, MOQ & Lead Time
A hot melt web quote relies on just a few basic parameters and knowing them from the outset speeds the process up. Your cost and lead time will depend on the variables below as opposed to a static price list; because a 15g/m PA web slit down to narrow will be a different cost and lead time than a 100g/m TPU web on release liner.
| Pricing / lead-time factor | How it affects the quote |
|---|---|
| Polymer family | PA and TPU cost more than EVA; sets the base |
| Areal weight & thickness | Heavier / thicker web uses more material per m² |
| Width & slitting | Custom slit widths add a converting step |
| Release paper | Adds a carrier consumable and lamination step |
| Custom melt point / color / formulation | Application-specific grades affect MOQ and lead time |
| Order volume | Sets MOQ tier and unit economics |
Send us your substrate material, bonding temperature your line is capable of reaching, desired width and weight, and whether release paper is needed. We'll respond with a grade match, minimum order quantity, delivery time and sample for trial. We'll gladly custom-develop for your application in terms of thickness, width, melt point, color and additive package upon request.
Tengyang isn't a drop-ship broker who delivers some generic roll; our hot melt webs are manufactured entirely in house - melting, casting, coating, slitting under one roof - over decades of production experience. This is how a batch COA is tied to an actual lot, and how custom melt point becomes an engineered formulation for your specific needs, not a sourced roll of the dice. Because consistency from batch to batch is the single highest risk for any new supplier, we've built our company around ensuring it-and therefore, eliminating a mismatching, out-of-spec roll is why this whole process exists.

Buyer advisory, de-risking a first order
For the first order with a new supplier, request the three safeguards for a brand switch: batch Certificate of Analysis (COA) linked to a specific lot, a sample roll on retainer from your actual order, and a laminating protocol you run with our hot melt webs and your specific substrate prior to production. Tengyang provides all three, plus defined defect handling so batch to batch consistency is something you can measure against a documented quality-management framework (ISO 9001), not just believe.

Hot Melt Adhesive Web, Frequently Asked Questions
Choose a web when you want a lighter, more flexible bond that adds minimal stiffness and can breathe through its open structure, common for thin fabrics and stretch seams. Choose a film when you need full-area sealing or a continuous barrier bond. Both come in the same polymer families (TPU, PA, PES, EVA, PO), so the material logic is identical; only the geometry changes. Tengyang supplies both.
Polyamide (PA) and polyester (PES) lead on laundering durability, both withstand repeated washing and dry cleaning, which is why they dominate garment interlining. TPU also holds up well to washing and cleaning agents. EVA is more economical but only fair on repeated wash, and basic PE fusibles resist washing but not dry cleaning.
Match it to the least heat-tolerant substrate in the assembly, then confirm against the web's activation window: EVA and low-temperature TPU activate near 70°C, PES around 125–135°C, and PA in the high tier near 150°C. Too low gives a weak bond; too high over-penetrates the fabric and stiffens the hand. Always validate on a sample of your own material.
Most often the cause with polyamide is absorbed moisture: PA absorbs ambient moisture, and that absorbed water can flash to vapour under the press and foam the bond line. Store PA stock dry, hold to a validated pressing window, and run a sample trial. Foaming can also come from a bonding temperature set too high for the substrate.
A web's open structure supports breathability, but it isn't guaranteed by the web alone. Add-on weight, melt flow, pressure and dwell time decide whether the pores stay open after lamination. For a breathable result, specify a lighter areal weight and a gentle process window, then confirm on your fabric.
At the bonding step, yes in a specific sense: a hot melt web is 100% solid and releases no solvent VOCs during bonding, unlike solvent adhesives that require drying and emission controls. We state this as a process fact rather than a broad environmental claim, the benefit is a solvent-free bonding step, not a blanket "green" label.
Store rolls in a cool, dry place and keep polyamide stock especially dry to avoid moisture pickup. Shelf life depends on polymer and storage conditions; we provide the storage window and dating for the specific grade you order.
A hot melt adhesive web is also called a hot melt adhesive mesh, the open, net-like adhesive is the same product. It differs from a fusible interfacing, which is a base fabric coated with adhesive on one side, and from a consumer heat activated adhesive for fabric. For joining two materials directly, whether as a hot melt adhesive film for textile fabric, an adhesive web for fabric, or a hot melt adhesive film for metal, the web sit between the layers and melts to bond them.
Yes. Tengyang produces to custom thickness, width, melt point, color and application-specific formulation, in both web and film forms, with or without release paper. Send your parameters for a matched grade and sample.
