Pe frosted bag has no toughness and will not burst easily. Good flexibility, not easy to wrinkle and deform. Its material feels soft, which can effectively prevent the surface scratch caused by the friction between the product and the bag, and the thickness can be adjusted freely. It has strong antistatic property and is widely used in general electronic products such as printed circuit boards. As an outer package, it can not only save cost, but also protect electronic products from electrostatic damage to electronic components caused by mutual friction between insulators, and prevent oxygen and moisture.
