There are common ziplock bags, self-adhesive ziplock bags, etc. It is a re-sealing plastic bag made of polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) through film blowing and hot-cutting machine bags. Common materials are PE, EVA, PET, composite bags, etc. Specifically, there are the following:



1. Polyethylene (PE): Polyethylene is a high molecular polymer of ethylene. It is thermoplastic. It is soft, has good water resistance, and low-temperature resistance, and is odorless, and non-toxic. As a material for making food packaging bags, these characteristics are: necessary.


2. Polypropylene (PP): non-toxic, odorless, high transparency, mechanical properties, surface strength, friction resistance, chemical corrosion resistance, moisture resistance are very good, widely used in the food industry, mostly used for the manufacture of films, composite materials The film has good transparency and surface gloss and can withstand a temperature of 120 degrees.


3. Polystyrene (PS): non-toxic, tasteless, odorless, good in coloring, higher in moisture permeability than polyethylene, low in moisture absorption, dimensionally stable, and has good luster.
