CPP Film It is called Filmcast polypropylene, also known as unstretched polypropylene Film, which can be divided into General CPP (General CPP, referred to as GCPP) Film and aluminized CPP (Metalize CPP, Metalize CPP, Metalize CPP, etc. MCPP) Film and Retort CPP (Retort CPP) Film, etc。
It is called Filmcast polypropylene, also known as unstretched polypropylene Film, which can be divided into General CPP (General CPP, referred to as GCPP) Film and aluminized CPP (Metalize CPP, Metalize CPP, Metalize CPP, etc. CPP is a polypropylene (PP) Film produced by the casting extrusion process in the plastics industry. This type of Film is different from BOPP(Bidirectional polypropylene) Film, which is a non-oriented Film. Strictly speaking, CPP Film only has a certain orientation in the longitudinal (MD) direction, mainly due to the nature of the process. By rapid cooling on the cold cast roller, excellent clarity and finish are formed on the Film MCPP Film and Retort CPP (RCPP) Film, etc。
-Compared with LLDPE, LDPE, HDPE, PET, PVG and other films, the cost is lower, the output is higher, the stiffness is higher than PE Film, the moisture and odor barrier is good, multi-functional, can be used as a composite material base Film, can be metallized, as food and commodity packaging and packaging, with excellent demonstration. The product can still be clearly visible under the packaging.
1, (composite film) clothing, knitwear and flower packaging bags; Document and album Film; Food packaging.
2, (aluminized Film) barrier packaging and decoration of metallized film. After vacuum aluminization, it can be combined with BOPP, BOPA and other substrates and used for high-grade packaging of tea, fried crispy food, biscuits, etc.
3, (cooking film) CPP has good heat resistance. Since the softening point of PP is about 140 ° C, this kind of Film can be used in hot filling, cooking bags, aseptic packaging and other fields. Coupled with excellent acid, alkali and grease resistance, it becomes the preferred material in the field of bread product packaging or laminating materials. It has safe contact with food, excellent demonstration performance, does not affect the flavor of the internal food, and can choose different grades of resin to obtain the required Character.
4, (functional film, also known as special film) potential uses also include: food packaging, candy packaging (twist film), pharmaceutical packaging (infusion bag), in the fields of albums, folders and documents instead of PVC, synthetic paper, self-adhesive tape, name card holders, circular folders and standing bag composite materials.
5, CPP new application markets, such as DVD and video box packaging, bread and pastry packaging, vegetable and fruit anti-fog Film and flower packaging, as well as synthetic paper for labels.
