Glassine Release Paper for Hot Melt Adhesive Film
In hot melt adhesive film production, the performance of the release liner directly affects coating quality, processing efficiency, and final product performance.
Among all liner materials, glassine release paper is widely recognized as the most cost-effective and stable solution.
SANLIN NEW MATERIALS CO., LTD is a professional manufacturer of glassine release paper, and approximately 80% of hot melt adhesive film manufacturers in China use our products, proving their reliability in industrial production.
What Is Glassine Release Paper?
Glassine release paper is a super-calendered, high-density paper coated with silicone to provide controlled release properties.
Key Features:
Ultra-smooth surface
High density and strength
Stable release force
Good heat resistance (120–160°C)
These features make it ideal as a release liner for hot melt adhesive film coating.
Why Glassine Release Paper Is Used in Hot Melt Adhesive Film
1. Ensures Uniform Adhesive Coating
The smooth surface of glassine paper allows:
Even adhesive distribution
Consistent film thickness
Defect-free surface
2. Provides Stable Release Force
During production (coating → cooling → winding → slitting), unstable release force can cause:
Film separation
Coating defects
Production instability
Glassine release liners offer consistent and controlled release performance.
3. Balanced Performance Across All Stages
Different stages require different release characteristics:
|
Stage |
Requirement |
|
Coating |
Medium-high release force |
|
Slitting & transport |
Stable medium release |
|
Final lamination |
Easy peel |
The most commonly used range: 8–12 gf/25mm
4. Compatible with Multiple Adhesive Types
Glassine release paper works well with:
TPU hot melt adhesive film
PES hot melt adhesive film
PA hot melt adhesive film
Release force can be customized based on adhesive system and thickness.
5. Cost-Effective vs PET Film Liners
Compared with PET liners:
Lower cost
Sufficient heat resistance
Better cost-performance ratio
Key Factors When Choosing Release Liner for Hot Melt Adhesive Film
When selecting a release liner, consider:
✔ Release Force
Must match adhesive type and thickness.
✔ Surface Smoothness
Affects final film quality.
✔ Tensile Strength
Important for high-speed coating.
✔ Silicone Coating
Single-side or double-side depending on application.
✔ Temperature Resistance
Must withstand coating temperature.
Common Problems with Poor Release Liners
Using low-quality release paper may result in:
Silicone transfer
Unstable release force
Difficult peeling
Film defects
Production downtime
This directly impacts product quality and efficiency.

FAQ – Hot Melt Adhesive Film & Release Liners
What release force is best for hot melt adhesive film?
Typically 8–12 g/in is recommended for balanced performance across production and application.
Base on different application and also has 60~80g/in ,80~100g/in ,200~300g/in .we can customized by customer 's requirement .
Is glassine paper better than PET liner?
For most applications, yes.
Glassine offers:
Lower cost
Good performance
Stable processing
PET is used only when higher temperature resistance is required.
Should I use single or double silicone coating?
Single-side: standard hot melt adhesive film
Double-side: special processes or anti-blocking needs
What grammage should I choose?
60gsm → thin films
80gsm → standard applications
90gsm → heavy-duty industrial use
Can release force be customized?
Yes. It depends on:
Adhesive type
Thickness
Production conditions
