What is Foam Release Paper?
Foam Release Paper is specially developed as a carrier material used in the continuous slabstock (PU) polyurethane foam production
process. It is also known as peelable PE-coated kraft paper for foam molding.
It serves as a release and separation layer during the processing of foam materials such as EVA, PE, PU, and rubber,
preventing adhesion while ensuring a smooth surface and easy demolding.

Slitting Width: 50mm – 2600mm (customizable)
Solutions by Industry
Prevents sticking & deformation
during heat foaming
Maintains dimensional stability under
high pressure & temperature
Provides a clean, smooth finish to
foam surface
Enhances automation & precision in
lamination and die-cutting
Application
EPE, PU cushioning foam, molded packaging pads
Challenge
Need thick foam to maintain shape and smooth outer surface
Heavy-duty release paper to prevent foam shifting or uneven curing
Clean release reduces scrap rate and improves appearance
Supports high-temp compression molding
Why Choose Our Peelable PE Coated Kraft Paper?
Specifically Designed for Foam Processing
Our release paper is engineered to withstand high temperatures without curling or wrinkling, making it ideal for EVA, PU, PE, CR, EPDM, and various other foam molding applications.
High Temperature Resistance
Capable of withstanding the heat and pressure during foam expansion (typically up to 150–180°C) without deformation or wrinkling.
Smooth Surface Finish
Ensures a flat and clean surface on the foam material after processing, making it easier for subsequent lamination, punching, or die-cutting.
