CPP protective film has very important practicality in major industries. Packaging and engineering in more and more industries are focusing on CPP protective film. CPP protective film includes CPP matte protective film, CPP transparent protective film, and CPP matte protection. Film, CPP co-extruded composite film, etc., are used in different industries.
The use of CPP protective film in the medical industry: The production line is required to be installed in a sterile room to prevent any form of contamination of the product, and it does not contain hygienic properties such as the migration of harmful substances. After being plated with aluminum, it can be compounded with BOPP, PET, BOPA, etc. as the packaging of tablets or powder drugs; co-extruded with high barrier materials such as EVOH to produce transfusion bags, blood collection bags, etc.
Application of CPP protective film for pesticide package: Through the modification and use of special materials, the solvent resistance, heat-seal strength and impact resistance of CPP film are greatly improved. It is used in the packaging of pesticides such as cream. The usual flexible packaging structure is CPP/AL/BOPET And CPP/PET aluminized/BOPET.
Use of composite film formed by co-extrusion of CPP protective film and PE: CPP film produced by modification can be directly extruded and compounded with LDPE and other film materials, which not only ensures the fastness of extrusion compounding, but also reduces the cost of compounding.
Using CPP protective film as the base material, processed into a highly transparent and flexible film Purpose: By using co-extrusion and blending technology, the CPP protective film has high transparency, high impact resistance, extremely soft hand feeling, and excellent resistance. Puncture performance and low temperature resistance performance, mainly used for food packaging frozen storage after cooking, also used in high-end clothing, T-shirts and underwear packaging, and can also be used for other heavy packaging.
CPP protective film can be processed into biodegradable film. Its use: CPP degradable film made of degradable masterbatch is added to PP, which can be basically degraded into inorganic matter by soil under natural conditions for 7 months to 12 months absorb. At present, some companies in Europe have successfully developed such masterbatch, and some domestic cast film factories are testing it.
