GCPP film
CPP film is cast polypropylene film, also known as polypropylene film does not stretch, according to different uses can be divided into general CPP (General CPP. Referred to as the GCPP) film. Aluminum Level CPP (Metalize CPP, referred to as MCPP) film and cooking class CPP (Retort CPP referred RCPP) films.
CPP film is got by the method of casting non- oriented polypropylene film.
CPP film has good transparency, high gloss, good stiffness, good wet resistance, heat resistance and excellent, easy-to-heat sealing characteristics.
After printed, CPP film is suitable for bag, garments, knitwear and flower bags; files and albums films; food packaging; barrier packaging and decoration of the metal film.
1, (lamination film-CPP film ) clothing, knitwear and flower bags; files and albums films; food packaging.
2, (aluminized-CPP film) barrier packaging and metal-film packing. After vacuum aluminum, laminating with BOPP, BOPA and other substrate materials used for composite and tea, crispy fried foods, biscuits and other high-grade packaging.
3, (cooking film-CPP film) CPP excellent heat resistance. The softening point of PP is about 140 ℃, such films can be used in hot filling, cooking bags, aseptic packaging and other fields. With acid and alkali resistance, excellent performance grease, making bread or laminated packaging material of choice for the field of materials.
4, (function film, also called special film-CPP film ) usage and application include: food packaging, candy packaging (twist), pharmaceutical packaging (infusion bag), in albums, folders and files and other fields instead of PVC, synthetic paper, adhesive tape, business card holder, ring stand bags of folders and composite materials.
5, the specifications are: Thickness:20-150 microns (UM), width :350-1500MM, length :2000-6000M
