Material:

Food packaging bags generally use PET film, PE film, OPP film and CPP film.

Characteristic:

PET film: This film is transparent, harder, and has good high temperature resistance. It has good printing effect. It is more suitable for food packaging. The feel of PET film is relatively crisp. .

PE film: The transparency is slightly inferior to CPP, but it is softer than CPP. PE film has better tensile properties and better tensile strength. There are two kinds of milky white PE and transparent PE, which have a soft hand feeling.

PA film (nylon): PA material is relatively tough, has good transparency, abrasion resistance and puncture resistance, is easy to be oxidized, and is easy to shrink and wrinkle. This material is suitable for packing similar bone products.

OPP film: The material is hard and cannot be stretched. The heat-seal type is very good, but the transparency is relatively general, the material is relatively brittle, and the hand feel is poor.

CPP film: CPP material is worse than OPP but better than PE in terms of transparency. The material is soft and resistant to high temperatures. It is a material that can be used for printing, but it is not easy to print.
