Do you know what materials are used for plastic packaging?

1.PE plastic packaging bags
Polyethylene (PE), referred to as PE, is a high molecular organic compound formed by the addition polymerization of ethylene. It is recognized as a good material for contact with food in the world. Polyethylene is moisture-proof, anti-oxidation, acid-resistant, alkali-resistant, non-toxic, tasteless, and odorless. It meets the hygienic standards for food packaging and is known as the “plastic flower”.
2. PO plastic packaging bags
PO plastic (polyolefin), referred to as PO, is a polyolefin copolymer, a polymer made from olefin monomers. It is opaque, brittle, and non-toxic. It is often used to make PO flat bags, PO vest bags, and especially PO plastic bags.
3. PP plastic packaging bags
PP plastic packaging bags are made of polypropylene. They are generally printed in color and offset printing processes. They are bright in color. They are stretchable polypropylene plastics and belong to a type of thermoplastic plastics. They are non-toxic, tasteless, and have a smooth and transparent surface.
4. OPP plastic packaging bags
OPP plastic packaging bags are made of polypropylene, bidirectional polypropylene, which is characterized by easy burning, melting and dripping, yellow on the top and blue on the bottom, less smoke after leaving the fire, and continued burning. It has the characteristics of high transparency, brittleness, good sealing, and strong anti-counterfeiting.
5. PPE plastic packaging bags
PPE plastic packaging bags are products produced by combining PP and PE. The product has the characteristics of dustproof, anti-bacteria, moisture-proof, anti-oxidation, high temperature resistance, low temperature resistance, oil resistance, non-toxic and odorless, high transparency, strong mechanical properties, high anti-explosion performance, strong puncture and tear resistance.
6. Eva plastic packaging bags
EVA plastic bags (frosted bags) are mainly made of polyethylene tensile materials and linear materials as raw materials, containing 10% EVA materials. Good transparency, oxygen isolation, moisture resistance, bright printing, bright bag body, can highlight the characteristics of the product itself as much as possible, ozone resistance, flame retardant and other characteristics.
7. PVC plastic packaging bags
PVC materials include frosted, ordinary transparent, ultra-transparent, environmentally friendly low-toxic, environmentally friendly non-toxic materials (6P does not contain phthalates and other standards), etc., and there are soft and hard plastics. It is safe and hygienic, durable, beautiful and practical, exquisite in appearance, diverse in style, and very convenient to use. Many high-end product manufacturers generally choose PVC bags for packaging, beautifying products and improving product grades.
