The commonly used materials of plastic packaging bags are as follows:

1. PE plastic packaging bag

Polyethylene (PE), abbreviated as PE, is a high-molecular organic compound made by addition polymerization of ethylene. It is recognized as a good food contact material in the world. Polyethylene is moisture-proof, oxygen-resistant, acid-resistant, alkali-resistant, non-toxic, tasteless, and odorless. It meets the hygiene standards of food packaging and is known as the “flower of plastic”.

2. PO plastic packaging bag

PO plastic (polyolefin), abbreviated as PO, is a polyolefin copolymer, a polymer made from olefin monomers. Opaque, crisp, non-toxic, often made PO flat bags, PO vest bags, especially PO plastic packaging bags.

3. PP plastic packaging bag

PP plastic packaging bags are plastic bags made of polypropylene. They generally use color printing and offset printing processes with bright colors. They are stretchable polypropylene plastics and belong to a type of thermoplastic. Non-toxic, tasteless, smooth and transparent surface.

4. OPP plastic packaging bag

OPP plastic packaging bags are made of polypropylene and bidirectional polypropylene, which are characterized by easy burning, melting and dripping, yellow on the top and blue on the bottom, less smoke after leaving the fire, and continue to burn. It has the characteristics of high transparency, brittleness, good sealing, and strong anti-counterfeiting.

5. PPE plastic packaging bag

PPE plastic packaging bag is a product produced by combining PP and PE. The product is dust-proof, anti-bacterial, moisture-proof, anti-oxidation, high temperature resistance, low temperature resistance, oil resistance, non-toxic and odorless, high transparency, strong mechanical properties, and anti-blasting High performance, strong puncture and tear resistance, etc.

6. Eva plastic packaging bag

EVA plastic bags (frosted bags) are mainly made of polyethylene tensile materials and linear materials, containing 10% EVA material. Good transparency, oxygen barrier, moisture-proof, bright printing, bright bag body, can highlight the characteristics of the product itself, ozone resistance, flame retardant and other characteristics.

7. PVC plastic packaging bag

PVC materials are frosted, ordinary transparent, super transparent, environmentally friendly and low-toxic, environmentally non-toxic (6P does not contain phthalates and other standards), etc., as well as soft and hard rubber. It is safe and hygienic, durable, beautiful and practical, exquisite in appearance, and diverse in styles. It is very convenient to use. Many high-end product manufacturers generally choose PVC bags to pack, beautifully install their products, and upgrade their product grades.

The content introduced above is some materials commonly used in plastic packaging bags. When choosing, you can choose suitable materials to make plastic packaging bags according to your actual needs.
