Cast polypropylene film (CPP) cast polypropylene film production process is the use of cast polypropylene film hard plastic film, it can be divided into ordinary cooking class CPP and CPP are two transparent film, excellent transparency, uniform thickness, and performance vertical and horizontal uniformity selling plastic film, generally used as an inner layer material composite film. Thickness of ordinary CPP film is generally between 25 ~ 50μm, and after OPP composite transparency is good, bright surface, feeling strong, general gift bags are used such materials. This film also has good heat sealability. The use of this new type of plastic composite plastic film production, made after food and beverage packaging once the packaging torn, coated with a special agent of the inner layer to absorb moisture from the air, with the polymer to react with a reactive group of the film will be like perforation like slowly broken down. According to foreign media reports, the German scientists using technology successfully developed a medical professional antibacterial plastic packaging. The package applies to milk and other liquid beverage packaging is an important change in food packaging technology. German processing factories and Packaging Technology Association, researchers used coating technology in plastic packaging film coated with antiseptic and antibacterial materials, alternative food preservatives added. Such coatings may be based on a composite resin material and special technology. Black plastic film, Red Plastic Factory (certification), Weinan plastic film provided by Xiong red plastic factory.
