CPE films, also known as cast PE film or cast polyethylene film, made of polyethylene as the primary material, are formed through a casting process. This film-making technology uses molten polymer extruded through a hole of a die and cooled on a cooling roller to form a film. Unlike the blow molding process, the casting process uses higher temperatures, which results in faster production speeds, better film strength, and elongation. Our cast polyethylene products are widely applied in diverse areas, including food packaging, drug packaging, and construction supplies. With our wide experience and expertise, we can provide the cast films of different types you require. CPE films are known for their high strength, high transparency, and excellent sealing features, which make them particularly popular in the food packaging industry. They keep food safe from moisture and oxygen, yielding a clear visual display. Furthermore, CPE films are widely used in pharmaceutical packaging, where these non-toxic and odorless properties ensure drug safety. The BOPE/CPE composite structure has a unique monoolefine structure, which makes it recommended for applications requiring high strength, weather resistance, and barrier properties. Functional requirements of CPE combined with other plastic films, including nylon, PET, and BOPP, are also possible. Tradsark was established in 2016 and is now one of the largest suppliers of cast polyethylene film (CPE) in China. We have six major warehouses nationwide, allowing us to process big orders and deliver them quickly.
