TPU Hot Melt Adhesive Film for Shoe Upper Mesh and Stitch-Free Reinforcement

Terminology note: stitch-free reinforcement means reducing sewn reinforcement steps on selected shoe upper parts. The TPU hot melt adhesive film still works as the heat-activated bonding layer between the upper material, reinforcement piece, TPU film or TPU trim.

Product Fit

This TPU hot melt adhesive film is positioned for footwear factories and shoe material converters that need a dry bonding layer for shoe upper mesh, stitch-free reinforcement using TPU hot melt adhesive film, TPU film or TPU trim overlay bonding and local shaping. It is not a universal shoe adhesive; sample approval should be based on the real upper material, coating, bonding position and flex test.

Key Features

• Flexible TPU bonding for shoe upper mesh, synthetic upper material and local reinforcement parts.
• Suitable for stitch-free footwear structures bonded with TPU adhesive film, overlay backing and die-cut shoe components after testing.
• Clean film handling compared with liquid glue, with roll, slit roll, sheet or die-cut supply options.
• Release paper, release film or liner-free options can be reviewed by grade and converting process.
• Sample direction can be selected by heat tolerance, hand feel, shaping need and final footwear test.

Recommended Applications

Suitable Bonding Materials

Common trial materials include shoe upper mesh, TPU film, TPU trim, PU leather, microfiber leather, nylon fabric, polyester fabric, coated shoe upper materials and selected synthetic footwear layers. Difficult coatings, low-energy surfaces and plasticized materials should be tested before bulk order.

Selection Notes Before Sampling

Sample Grade Selection

The following VELNORA public model codes are converted from approved internal line-card data. They are starting points for sample selection, not a guarantee for every footwear substrate or process.

Basic Processing Guide

Start with small sample trials and record the real interface temperature, pressure, dwell time and cooling method. For ZF-8815, the approved reference service condition is 0.1-0.4 MPa, 140-180 C and 8-20 seconds. For ZF-5180, the approved reference service condition is 0.1-0.4 MPa, 80-110 C and 5-20 seconds. Adjust one variable at a time and compare peel strength, edge lifting, surface marks and bending performance after conditioning.

Customization And Sample Support

VELNORA can support roll, slit roll, sheet and die-cut sample directions. For a useful recommendation, send the shoe upper material, bonding position, target thickness, liner handling method, machine type, working temperature range and the test standard used by your buyer.

Quality Control Summary

Before sample approval, check film appearance, thickness, roll width, liner condition, cutting behavior, bonding trial result and packed roll condition. For footwear applications, repeated bending, edge-lift inspection, heat aging and appearance after cooling are more useful than a quick hand-peel check alone.

FAQ

Which TPU grade direction fits shoe upper mesh?

For shoe material surface use, TPU mesh bonding and shaping, start with ZF-8815. If the upper material is more heat-sensitive or the buyer needs a lower-temperature trial direction, ZF-5180 can be reviewed as a sample option.

Can this film be die cut for stitch-free shoe parts?

Yes. TPU hot melt adhesive film can be supplied as roll, slit roll, sheet or die-cut piece. The liner choice should be confirmed according to positioning, die cutting and peeling method.

Can it bond TPU film to mesh fabric?

It can be tested for TPU film, TPU trim or overlay bonding to mesh and selected shoe upper materials. Final approval depends on coating, surface energy, pressure uniformity and flex testing.

What information should I send before requesting samples?

Send shoe upper material names, photos, bonding position, current film thickness if available, equipment type, temperature and pressure settings, target tests and expected supply form.
