CPP film, also known as cast polypropylene film, is a polypropylene film produced by the casting process. It is divided into general CPP (GCPP), aluminized grade CPP (MCPP) and cooking grade CPP (RCPP) films. Wide application: Due to the above advantages, CPP film is widely used in the packaging of textiles, flowers, food, and daily necessities. In addition, CPP film also has the characteristics of lower cost, higher output, higher stiffness than PE film, excellent water vapor and odor barrier, can be used as a composite material base film, and can be metallized.

Metallized CPP film is a film made of polypropylene material with special process and special specifications, which belongs to high-end CPP film products. Its main feature is the metallization treatment, that is, a layer of metal, usually aluminum, is plated on the surface of the film through a special process to enhance the barrier performance and aesthetics of the product. This treatment not only enhances the physical properties of the film, such as heat seal strength, barrier and aesthetics, but also provides additional functional properties, such as barrier ability to oxygen and water molecules, thereby extending the shelf life of food and other products. Metallized CPP film is usually used in application scenarios that require high barrier properties, such as high-end food packaging, pharmaceutical packaging, etc., to ensure product quality and safety.
