按材质可分为OPP、CPP、PP、PE、PVA、EVA、复合袋、共挤袋等。 Plastic woven bags can be divided into OPP, CPP, PP, PE, PVA, EVA, composite bags, co-extruded bags and so on.Non-toxic, compoundable, better transparency than PE, slightly worse hardness, soft texture, transparency of PP, softness of PE.
CPP film is cast polypropylene film, also known as unstretched polypropylene film. It can be divided into general CPP (General CPP, GCPP) film, aluminized CPP (Metalize CPP, MCPP) film and Cooking grade CPP (Retort CPP, RCPP for short) film and so on.
The main characteristics of CPP film include:
Compared with other films such as LLDPE, LDPE, HDPE, PET, PVG, etc., the cost is lower and the output is higher.
Higher stiffness than PE film.
Excellent barrier to moisture and odor.
Versatile, can be used as a composite base film.
Can be metallized.
As food and commodity packaging and outer packaging, it has excellent demonstrability, which can make the product still clearly visible under the packaging.
