Food packaging material has used in the general PET film, PE film, PA film, OPP film, CPP film, etc.
PET film: this film super transparent, material is hard, and high temperature resistance, good printing effect, is suitable for food package, PET film feels feel particularly fragile, in your hands can rustle slightly crunchy.
PE film: the less transparency CPP, but is soft than CPP, PE film better tensile properties, tensile force is better.Has two kinds of milky white and transparent PE PE (HDPE/LDPE/LLDPE), feel is soft.
PA film (nylon) : PA material to compare tenacity, good transparency and abrasion resistant to Pierce, easy to oxidation, prone to shrinkage and crinkle, this material is suitable for products similar to bone.
OPP film: material is hard, and cannot be stretching, heat sealing type is very good, but transparency is more general, brittle material, feel bad.
CPP film: transparency than OPP CPP material is poor but better than PE, soft material and high temperature resistant, can be used to make printed materials, but not easy to print.
