Kraft paper, commonly PE-coated and peelable, plays a vital role in polyurethane (PU) foam manufacturing—particularly in continuous slab stock production. It acts as a non-stick liner and protective layer, allowing for easy foam release, minimizing waste, and ensuring a smooth surface finish. it is durable and high in strength which makes it ideal for handling foam products and packaging

Key Roles in the Foam Industry

• Separator: Prevents foam from sticking to machinery, molds, or conveyor surfaces during production.
• Packaging & Protection: Provides tear resistance and cushioning during transport and storage.
• Customizable Barrier: Available with specialized coatings like peelable PE for enhanced performance.

Types of Kraft Paper

• Peelable PE-Coated Kraft Paper: Offers a clean release, moisture resistance, and UV protection for foam blocks.
• Regular Kraft Paper: Regular kraft paper is used for foam protection and general packaging.
• MG (Machine Glazed) Kraft Paper: It is ideal for continuous foam production lines

Benefits

• Cost-Effective: A reliable, economical choice for foam manufacturers
• Eco-Friendly: Recyclable and often produced from sustainable sources
• Improves Efficiency: Minimizes equipment cleanup and production downtime
• Enhances Foam Quality: Supports cleaner edges and smoother surface finishes
• Moisture & UV Protection: Safeguards foam during and after production
