blog about Why More Waterproof Membrane Manufacturers Choose UV-Cured PP Release Film

Summary

As the waterproofing industry continues moving toward higher performance and environmentally friendly manufacturing, release liner technology is becoming increasingly important.

For SBS and APP modified bitumen waterproof membranes, the release film directly affects:

• Adhesive protection
• Product stability
• Construction efficiency
• Storage performance
• Final waterproofing reliability

Traditional release liners often struggle to meet modern production and construction requirements. This is why more manufacturers are switching to UV-Cured PP Release Film solutions.

UPASS provides high-performance UV-cured PP release film specially designed for self-adhesive waterproof membrane applications.

Many conventional release liners still use outdated coating systems and low-performance substrates.

This may create several common issues:

Uneven peeling performance can reduce installation efficiency.

Some liners shrink or deform under high-temperature storage conditions.

Low coating stability may contaminate the adhesive surface.

Weak barrier performance can affect membrane appearance and cleanliness.

These problems directly impact membrane quality and customer satisfaction.

UPASS combines advanced UV silicone coating technology with high-quality PP film structures to improve waterproof membrane performance.

Compared with traditional solvent-based systems, UV curing technology offers:

• Faster curing speed
• More stable coating uniformity
• Lower VOC emissions
• Improved production efficiency

This helps manufacturers achieve cleaner and more stable production.

UPASS UV-Cured PP Release Film provides excellent dimensional stability during:

• High-temperature transportation
• Outdoor storage
• Roofing construction

The product can withstand temperatures up to 140℃–160℃, making it suitable for SBS and APP waterproof membrane applications.

The UV silicone coating layer provides:

• Smooth peeling
• Controlled release force
• Reduced adhesive damage
• Better installation consistency

Customized release force options are available according to different membrane systems.

UPASS release film provides:

• MD tensile strength ≥36 MPa
• TD tensile strength ≥23 MPa
• Excellent elongation performance
• Stable winding properties

These characteristics improve converting efficiency during membrane production.

UPASS UV-Cured PP Release Film provides subsequent adhesion above 90%, helping maintain the adhesive activity of SBS and APP modified waterproof membranes after liner removal.

The film also helps:

• Reduce asphalt migration
• Prevent contamination
• Improve shelf-life stability

UPASS UV-Cured PP Release Film can be customized according to different application requirements.

• Thickness: 0.03mm–0.15mm
• Width: 100mm–2000mm
• Coating: Single-side or double-side silicone coating
• Color: Black, Grey, White, Blue, Green, etc.
• Release force: customizable

UPASS UV-Cured PP Release Film is widely used in:

• SBS modified bitumen waterproof membranes
• APP modified waterproof membranes
• Roofing waterproof systems
• Butyl waterproof tapes
• Construction sealing materials

The product helps improve both manufacturing efficiency and construction performance.

As waterproof membrane manufacturers continue pursuing higher quality and more efficient production, release liner performance becomes increasingly important.

UPASS UV-Cured PP Release Film combines:

• Advanced UV silicone coating technology
• Stable release performance
• Excellent heat resistance
• Reliable adhesive protection

to support modern SBS and APP waterproof membrane manufacturing.

With cleaner production and better construction performance, UV-cured PP release film is becoming a preferred solution for the next generation of waterproofing systems.
