In the production of plastic bags for vest bags in Shandong Province, plasticizers are usually added to improve their performance. The following are the plastic bags produced by Anhui Hongyin Packaging Co., Ltd.
PVC full name PVC, the main component is PVC, the specific gravity is 1.38g per cubic centimeter, PVC resin is white or light yellow powder. According to different uses, different additives can be added, PVC plastics can present different physical and mechanical properties. Adding a proper amount of plasticizer to PVC resin can make various hard and soft transparent products. PVC has good electrical insulation performance and can be used as low-frequency insulation material with good chemical stability.
Due to the poor thermal stability of PVC, heating for a long time will lead to the separation and release of HCl gas, making PVC discoloration, so its application range is limited, and the use temperature is generally between - 15 ℃ and 55 ℃. PVC itself, but in the production process added lead, and lead is toxic, combustion can produce chlorine, chlorine is toxic, so its products generally do not store food and drugs.
Plasticizer itself is toxic, tasteless, light and heat stable high boiling point compound. The production of plastic bags is commonly used in phthalate plasticizers. It can usually be mixed with resin. Its role is to increase the plasticity and flexibility of plastic, reduce brittleness and make it easy to form process. The above is about the introduction of plastic bag plasticizer. Welcome to Anhui Hongyin Packaging Co., Ltd. to purchase plastic bags and food compound bags.
