What Kind Of Material Is Usually Used In Food Packaging Bags?

- Jun 30, 2019-

Material:

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

Characteristic:

PET film: This film is ultra-transparent, hard material, high temperature resistant, and has good printing effect. It is more suitable for making outer packaging bags for food. PET film feels particularly brittle, and it can make a rustling sound in the hand.

PE film: transparency is slightly inferior to cpp, but softer than cpp, PE film has better tensile properties and better tensile strength. There are two kinds of milky white PE and transparent PE (HDPE/LDPE/LLDPE), which is soft to the touch.

PA film (nylon): PA material is tough, transparent, wear-resistant and puncture-resistant, easy to be oxidized, easy to shrink and wrinkle. This material is suitable for bone-like products.

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

CPP film: CPP material is less transparent than OPP but better than PE. The material is soft and high temperature resistant. It can be used as printing material, but it is not easy to print.
