How many kinds of packing bags are there in the packaged foods?
PE's softness and mechanical properties are worse than those of PP. It represents shopping bags, plastic wrap, garbage bags and so on.PP is stiffer, anisotropic (with a notch that is easily ripped), has good mechanical properties, and is superior to PE in high-temperature performance, representing bread bags.I wonder if this answer has met your requirement.
The material is generally PE and PP.Compared with non food packaging, it does not contain plastic additives, and will not release toxic substances during use. For example, the more severe plasticizer in the front can cause cancer, and is used in PVC packaging. PVC used in the past, but because of its insecurity, it is now being gradually replaced by PE plastic wrap.
You ask about food plastic packaging, it is generally packaged with composite bags, composite materials, polyethylene (PE), polypropylene, nylon, polyester. These are the main membranes. The film is made of stretch film and blow film. Dry frozen goods, generally cooked with PET/PE., such as high temperature, it is generally nylon, composite CPP, or other composite, many kinds. I am in Dongguan, Humen, food packaging, such as alcoholic peanuts, bags, red dates bags, mask packaging bags, washing powder bags, areca bags, milk powder bags, small fish bags.
