Sterilizable Packaging Outstanding Ink and Coating Adhesion CPP Film for Food Packaging

Sterilizable Packaging Outstanding Ink and Coating Adhesion CPP Film for Food Packaging

The CPP Film, a cast polypropylene film, is also called an unstretched polypropylene film.
CPP is a polypropylene (PP) film produced by a cast extrusion process in the plastics industry. This type of plastic film is different from BOPP (biaxially-oriented polypropylene) film and is a non-oriented film. Strictly speaking, the CPP film has only a certain-orientation in the machine direction (MD) direction, mainly due to the nature of the process. Excellent clarity and finish are formed on the film by rapid cooling on a chill roll.

CPP film treated with one side corona is widely used for printing, food packaging, textiles packaging, twist wrapping, floral wrapping, medical and hygiene film, retort packaging, deep freeze application as well as lamination with BOPP or PET film for surface protection with barrier properties.
It is workable on both flexographic and rotogravure printing, making foodstuff products packaged on high-speed packaging machines.

As a professional CPP Film China manufacturer, we are holding monthly capacity 4,000 MTs, powered 6 multi-layer co-extruded cast film production lines (7 meter wide as max., 300m/min as max), 5 high-speed automatic tension slitting machines, 3 international advanced vacuum aluminum plating production equipment, yielding thickness from 18μm to 120μm.

We are committed to serving a very good price CPP film while maintaining high product quality.
The certificates our product granted include MSDS, FDA, RoHS, REACH and so on.
