TPU Hot Melt Adhesive Film for Leather Goods and Luggage
TPU Hot Melt Adhesive Film for Leather Goods and Luggage
TPU adhesive film for leather goods and luggage is a flexible dry-film bonding layer for PU leather, microfiber leather, lining fabric, luggage panels, handle reinforcement and local backing structures. It helps converters bond leather-like surfaces to lining or reinforcement layers while keeping clean edges and flexible handling.

Product Fit
This TPU hot melt adhesive film is positioned for leather goods, PU leather accessories, luggage lining, bag reinforcement and flexible composite bonding. It is useful when buyers want a dry adhesive film instead of liquid glue and need cleaner handling, die-cut positioning or roll-to-roll converting.
Final grade selection should be tested on the real leather, microfiber, lining fabric, foam, board or coated textile because surface finish and heat tolerance can strongly affect bonding.
Key Features
- Flexible TPU adhesive film for soft leather goods and luggage structures.
- Suitable for roll, slit roll, sheet and die-cut supply.
- Can support local reinforcement, lamination and edge-wrap bonding after sample testing.
- Available with release paper, release film or liner-free handling by grade.
- Designed for sample-based selection rather than one universal process setting.
Recommended Applications
| Application Area | Typical Product / Bonding Position | What To Confirm |
|---|---|---|
| Leather goods lamination | Wallets, organizers, small leather goods and PU leather surface-to-backing lamination | Coating tolerance, glue mark control, hand feel and appearance after cooling. |
| Luggage lining and panel bonding | Inner lining, fabric-to-foam, fabric-to-board and local panel lamination | Flatness, bubbling, edge lifting and dimensional stability after bending. |
| Bag reinforcement parts | Handles, strap anchors, corners, edge-wrap zones and hardware backing areas | Peel strength, flex resistance, local thickness and whether the reinforcement telegraphs through the surface. |
| Decorative trim and logo bonding | Trim details, labels, decorative layers and die-cut bonding pieces | Die-cut cleanliness, positioning accuracy and surface marking on light-colored materials. |
Suitable Bonding Materials
Common trial materials include PU leather, microfiber leather, coated leather, nylon fabric, polyester lining, fabric-to-foam structures, selected TPU materials, ABS or PC support sheets and luggage board structures. Difficult coatings, oily surfaces, plasticized materials and low-energy surfaces should be tested before bulk order.
Selection Notes Before Sampling
| Selection Item | What The Buyer Should Check |
|---|---|
| Substrate finish | PU coating, microfiber surface, textile backing, foam density, board layer and any oil, silicone or softener that may reduce adhesion. |
| Appearance requirement | Check glue marks, surface embossing, strike-through, color change and edge visibility on the real leather or luggage material. |
| Flex and aging demand | Confirm bending, folding, heat storage, humidity aging and final peel-strength requirements before bulk order. |
| Liner and converting | Choose release paper, release film or liner-free handling according to die cutting, positioning and lamination workflow. |
| Storage before trial | Keep film sealed in a cool, ventilated place; avoid moisture, dust and long open-air exposure before sample bonding. |
Sample Grade Selection
| Public Code | Material | Melting Point Reference | Starting Service Conditions | Temperature Range | Sample Direction |
|---|---|---|---|---|---|
| ZF-5180 | TPU | 75-80 C | 0.1-0.4 MPa, 80-110 C, 5-20 s | -20 C to 80 C | Lower-temperature direction for PU leather, microfiber, nylon, PC/ABS support and textile-lamination trials. |
| ZF-6238 | TPU | 95-100 C | 0.1-0.4 MPa, 120-140 C, 5-20 s | -20 C to 80 C | General leather, PU, microfiber, nylon and textile bonding direction when a stronger process window is needed. |
| ZF-7325 | TPU | 75-80 C | 0.1-0.4 MPa, 110-130 C, 5-20 s | -20 C to 70 C | Lower-melting sample direction for leather goods, textile bonding and heat-sensitive composite structures. |
The values above are selection references from approved VELNORA model data. Final processing settings should be confirmed with the actual equipment, material stack and buyer test method.
Basic Processing Guide
- Clean dust, oil, release agents and loose coating from the bonding surface before trial.
- Start from the recommended grade direction and adjust temperature, pressure and dwell time one variable at a time.
- For PU leather and microfiber, check surface marks, softness and edge lifting after cooling.
- For luggage panels, test bending, peeling, bubbling and heat/humidity aging where relevant.
Customization And Sample Support
VELNORA can review roll width, slit width, sheet size, die-cut form, liner type and sample grade direction according to your material stack. Please provide substrate photos or samples, product structure, bonding equipment, target temperature range and the approval test you plan to use.
Quality Control Summary
For leather goods and luggage use, sample approval should include film appearance, thickness and width, liner condition, melt behavior, initial peel, cooled appearance, bending resistance and storage condition. Certification or long-term performance claims should be confirmed by the buyer’s own test standard.
FAQ
Can this TPU film bond real leather?
It can be tested on real leather, but leather finish, oil content, coating and heat tolerance vary widely. Sample bonding is required before bulk production.
Is it suitable for PU leather luggage panels?
Yes, TPU film is commonly evaluated for PU leather, microfiber, lining fabric and flexible luggage structures. The buyer should confirm appearance, edge lifting and bending performance on the real panel.
Can the film be die cut for bag reinforcement parts?
Yes. Roll, sheet and die-cut supply can be discussed. Liner choice should match the cutting, positioning and heat-press process.
Which information helps VELNORA recommend a sample direction?
Share the substrate, coating type, film thickness target, bonding equipment, temperature limit, required tests and whether the part is for lining, handle reinforcement, edge wrap or surface lamination.
