Antistatic PE bag is made of LDPE + LLDPE + antistatic masterbatch + Color Masterbatch + stabilizer mixed blown film, then heat sealed and cut off. This product has all the characteristics of ordinary PE bag and anti-static function. It is widely used in general electronic products, such as printed circuit board, etc. As an outer package, it can not only save cost but also protect electronic products from electrostatic damage caused by friction between insulators.

Low density polyethylene (LDPE): it is a thermoplastic resin made of ethylene by polymerization. It is nontoxic and feels like wax block. It has good low temperature resistance. The minimum temperature can reach 10-100 ℃. Good chemical stability, resistant to acid and alkali corrosion. It is insoluble in general solvents at room temperature, with small water absorption and excellent insulation, but poor heat resistance and easy aging. The properties and varieties of polyethylene depend on its molecular structure and density. Filler (anti-static masterbatch): it can improve the strength and heat resistance of the plastic, improve the mechanical strength at the same time, and fill in the anti-static masterbatch, so that the product has a good anti-static effect. Plasticizer: it can increase plasticity and softness of plastic, reduce brittleness and make plastic easy to process. Add plasticizer to low-density polyethylene, non-toxic, odorless, light and heat stable organic compounds with high boiling point. Add plasticizer in a proper amount. Adding more plasticizer will make the plastic too soft, and adding less plasticizer will make the material harder and easy to crack. Stabilizer: it is mainly used to prevent polyethylene from being decomposed and damaged by light and heat during processing, and to extend its service life. Common stabilizers include stearate and epoxy resin, etc. Color Masterbatch: also known as colorant, it can make products have bright and beautiful colors, and can be made into various colors according to requirements. Common organic dyes and inorganic pigments. Lubricant: mainly to prevent the plastic from sticking to the mold when forming, and to make the product smooth and beautiful. Antioxidant: mainly to prevent polyethylene from being oxidized during heating, making PE bag yellow, tearing, etc.

It is widely used in general electronic products such as printed circuit board, and its material feels soft. As an outer package, it can save cost and protect electronic products from electrostatic damage to electronic components due to friction between insulators. The antistatic bag is the best packaging material for printed circuit board, which can release the static electricity of printed circuit board and avoid damage. The technical specifications are as follows: in accordance with mil-b-81705b; the resistance of internal and external surfaces is 108 Ω -- ≤ 1011 Ω. The electrostatic discharge time is less than 2 seconds.

Generally, the nontoxic plastic bag is composed of polyethylene film, which is milky white and translucent. If you can't use one layer of hair, you can use several layers of plastic bags to fold up. The effect will be obvious. It's lubricated by hand, like a layer of wax on the surface. If you shake hard, there's a sound of brittle ears. If it's nontoxic plastic bag, you will encounter The fire is easy to burn, and the flame is yellow, and there is mucus dripping when burning, and there is the smell of candle burning.

The toxic plastic bag is generally made of PVC film. If it is not pigmented, it is transparent, and the surface feels sticky. If you shake hard, there will be a low voice, and it is not easy to burn when encountering a flame, as long as it leaves the flame, it will go out.
