What are the characteristics of PO plastic bags in general?
PO plastic bags usually what are the characteristics?
1, PO plastic bags high transparency, high brightness.
2, PO plastic bags, tensile strength, impact resistance is strong, make the product packaging after crisp degree good, not easy broken, broken.
3, PO plastic bags, low temperature resistance performance is good, not easy ageing. - after the product packaging + 50 ℃ 90 ℃, not deformation, contractive, not broken, hard brittle.
4, PO plastic bags density is only 0. 92, due to the high tensile strength PO film, its packaging does not drop, so when using the PO packing product, the cost per unit will not rise, and the effect will be better.
5, PO plastic bags, avirulent insipidity, use and processing process does not produce toxic or harmful gases. In line with international food and medical health standards, will not change the flavor and quality of packing materials.
6, PO plastic bags good toughness and high tensile strength. Polyvinyl chloride PVC low tensile strength, easy to aging, easily damaged, when the low temperature brittle crack, temperature contraction deformation easily and by packaging to change shape.
PO plastic bags is a kind of very light material, with a very low temperature heat can make it soft, follow one's inclinationsly into various shapes. Plastic products colorful, light weight, not afraid to fall, economic and durable, it was not only to the life of people brought many convenient, but also greatly promoted the development of industry. Widely used in chemical industry, light industry, food, textile, etc.
