CPP (Cast Polypropylene) film, renowned for its excellent physical properties and versatility, finds extensive use across multiple industries. In the food packaging sector, CPP film is a popular choice. Its high transparency showcases products attractively, while its good moisture resistance keeps food fresh, making it suitable for packaging baked goods, fruits, vegetables, and frozen foods. Moreover, it has good heat - sealability, allowing for the creation of airtight packages, which is essential for preserving the flavor and quality of food items. In the manufacturing of flexible pouches and bags, CPP film plays a crucial role. It can be easily combined with other materials, such as PET or aluminum foil, to form multi - layer structures with enhanced barrier properties. These multi - layer pouches are widely used for packaging liquids, powders, and snacks, offering convenience and protection during storage and transportation. The label industry also benefits from CPP film.
