Core Material Solutions

Industrial-grade materials covering soft, firm, glossy, matte, and ultra-thin leather for mass production.

PA Hot Melt Adhesive for PU PVC Leather
PA (Polyamide)

General Purpose for Regular PU/PVC Leather

Offers balanced bonding stability, wash resistance, and low yellowing. The leather surface remains flat without bulging. The most versatile material for the leather industry.

Suitable Leather

PU/PVC faux leather, bag linings, leather labels, wipe-clean daily goods.

Limitations

Moderate elasticity. Not for highly elastic soft genuine leather.

PES Hot Melt Adhesive for Outdoor Leather
PES (Polyester)

For Outdoor Leather & Weather-Resistant Goods

Industry-leading hydrolysis resistance, aging resistance, and UV resistance. Does not delaminate or yellow under long-term UV and humid conditions.

Suitable Leather

Outdoor bags, automotive interior seats, high-frequency washable workwear leather.

Limitations

Stiffer hand feel. High processing temp requires strict control on thin leather.

TPU Hot Melt Adhesive for Genuine Leather
TPU (Polyurethane)

For Genuine Leather, Soft Microfiber & Flexing

High elasticity and ultra-soft feel. Fully follows the flexing and stretching of the leather without restricting elasticity. Withstands hundreds of thousands of flexes.

Suitable Leather

Standardized Lamination Parameters

Leather is sensitive to high temperature. Follow these guidelines to prevent wrinkling, marring, and coating fragility.

Material Temp (℃) Pressure (MPa) Time (s) Cooling Requirement
PA Film/Mesh 120-140 0.3-0.5 10-15 Room temp natural cooling – shape to prevent rebound.
PES Film/Mesh 140-160 0.4-0.6 15-20 Forced air cooling – prevent high-temp sticking.
TPU Film/Mesh 100-120 0.2-0.4 8-12 Room temp cooling, low pressure shaping.
EVA Film/Mesh 80-100 0.2-0.3 5-10 Rapid forced air cooling – prevent heat shrinkage.

Common Selection Mistakes & Solutions

Avoid frequent production problems such as surface scorching, stiffness, and wash-induced failure.

Using PES/PP on genuine leather/soft microfiber

Leather becomes stiff overall, flex cracking occurs, hard edge marks appear.

Solution

Switch to TPU film/mesh – high-elastic flexible bonding, retains leather's natural softness.

Using high-temp PES/PP on glossy/heat-sensitive leather

Leather surface marring, fogging, shrinkage, coating melting.

Solution

Switch to EVA ultra-low temperature film/mesh (80-100°C) to protect leather gloss.

Using closed film on breathable leather goods

Moisture buildup inside leather, stuffiness, long-term use causes mildew.

Solution

Replace with corresponding mesh for all breathability requirements to preserve vapor transmission.

Using EVA on washable leather goods

Blistering, delamination, hydrolysis of glue layer after 1-3 washes.

Solution

For regular washing: PA; for outdoor high-frequency washing: upgrade to PES.

High-Frequency FAQ

Expert answers for leather hot melt bonding selection and processes.

For genuine leather bonding, should I use film or mesh first?
For genuine leather, the first choice is TPU mesh – high-elastic, soft, non-stiff, does not damage leather texture, suitable for repeated flexing and body-contact applications. If waterproofing or anti-color-bleed is needed, use TPU film. Never use PP or PES stiff high-temperature materials.
How to choose between film and mesh? One-sentence rule.
If you need breathability, hand feel retention, large-area bonding → choose mesh. If you need waterproof sealing, anti-color-bleed, shaping, edge sealing → choose film. Never use film for breathability requirements.
Why does leather wrinkle or shrink during lamination?
The main reasons are too high temperature, too high pressure, and too long press time. Leather is heat-sensitive. Soft, thin, or glossy leather requires low temperature, low pressure, and short press time. Prefer EVA or TPU low-temperature materials.
How to prevent cracking for high-frequency flexing leather goods like footwear?
Always use TPU film or TPU mesh. Rely on its ultra-high elasticity to follow leather deformation. Combine with low temperature, low pressure lamination process. Withstands hundreds of thousands of flexes without cracking or delamination.
