What is Cross linked Shrink film? and and How It Work in Food and Non-food Packaging?
Cross-linked shrink film is a type of POF shrink film that undergoes a chemical process called “cross-linking.” This process involves creating chemical bonds between the polymer chains in the film, which strengthens the material and alters its properties. The result is a film that has enhanced physical strength, heat resistance, and durability. Cross-linked shrink films are known for their high shrinkage ratios, meaning they can tightly conform to products with complex shapes, offering a smooth, tight, and secure wrap.With crosslink technology,is the universal film. This versatile shrink film is designed to be very user friendly.and offers excellent shrinkage & burn through resistance, strong seals & a wide sealing temperature range, and outstanding puncture & tear resistance. It is suitable for nearly all packaging systems in use today.
