Heat seal BOPE film, also known as heat-sealable biaxially oriented polyethylene film, is a type of polyethylene film produced through the biaxial stretching process, featuring excellent heat-sealing properties. It builds upon the high strength of traditional BOPE films and adds the ability for direct heat sealing, making it widely used in the packaging industry.
The heat-sealed BOPE film integrates outstanding mechanical properties (high strength, high puncture resistance), excellent heat-sealing performance, high transparency and glossiness, as well as environmentally friendly characteristics that are conducive to recycling.
