When it comes to food packaging , most people only know that it is made of plastic bags , which are made of polyethylene chemical materials. In the process of making food packaging bags, no one would say that this chemical material is divided into more detailed ingredients. Therefore, some people will ask what are the food packaging materials? Below the Jiuzhi Plastics Network Xiaobian will bring you to understand.
The material of the food packaging bag is not divided into a single layer material and a composite material when the bag is made, and is roughly classified into OPP material, PET material, PA material, AL material, CPP material, LDPE material, and the like.
OPP material can be further divided into BOPP, OPP matt, KOPP, the thickness of this material is 1.9C/2.3C/3.1C, and the minimum number of meters in a roll is 6000 meters;
PET material can be further divided into PET, VMPET, KPET, the thickness of this material is 1.2C, the lowest meter of a roll is 8000 meters;
PA material is also called nylon NY, the thickness of this material is 1.5C, and the lowest meter of a roll is 6000 meters;
AL is made of aluminum foil, the thickness of this material is 0.7C, and the minimum number of meters in a roll is 6000 meters;
CPP material can be divided into CPP, RCPP, VMCPP, which is customizable, and the quantity of a roll of material can also be customized;
The thickness of a LDPE material and the number of rolls are as customizable as CPP.
