Types of CPP film
(1) Metallized CPP film
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.
(2) Retortable CPP film
Retortable CPP film is a film with good heat sealing properties, mainly used for food
packaging. The thickness of retortable CPP film is generally between 60 and 80 μm, and it can
withstand high-temperature cooking at 121°C for 30 minutes. It has good oil resistance and air
tightness, as well as high heat sealing strength. This film is particularly suitable for the
inner layer of meat packaging. Due to its excellent heat resistance and oil resistance, it can
maintain the freshness and safety of food. In addition, retortable CPP film also has good heat
sealing properties, which can maintain the integrity and nutrition of food during
high-temperature cooking.
(3) CPP anti-fog film
CPP anti-fog film is a polypropylene film produced by a three-layer co-extrusion process and a
cast film. It is corona treated on one or both sides and has a unique anti-fog function. It can
prevent water vapor from forming fog on the surface of the film, thereby maintaining high
transparency and good shelf performance and display. This film not only has good moisture
resistance, heat resistance and easy heat sealing, but also has high slip and impact resistance,
excellent antistatic properties, high strength when combined with other materials, and is
particularly suitable for use in frozen environments. It can keep the packaged objects clear and
visible and extend the shelf life.
(4) Transparent CPP film
Transparent CPP (Cast Polypropylene) Film offers excellent clarity, high tensile strength, and
superior heat resistance, making it ideal for flexible packaging, food wrapping, and lamination
applications. It provides excellent moisture resistance, durability, and sealing performance,
ensuring product freshness and protection. Available in various thicknesses and roll sizes.
