The main hazards of blister material PVC of blister machine

Polyvinyl chloride is also a commonly used plastic, which is a resin composed of polyvinyl chloride resin, plasticizer and anti-aging agent, and is not toxic by itself. However, the main auxiliary materials such as plasticizers and antioxidants added are toxic. The plasticizers in daily PVC plastics mainly use dibutyl terephthalate, dioctyl phthalate, etc. These chemicals All are toxic, and lead stearate, an antioxidant for polyvinyl chloride, is also toxic. Lead will be precipitated when polyvinyl chloride (PVC) products containing lead salt antioxidants come into contact with ethanol, ether and other solvents. Polyvinyl chloride containing lead salt is used as food packaging and when it encounters fried dough sticks, fried cakes, fried fish, cooked meat products, cakes and snacks, lead molecules will diffuse into the oil, so polyvinyl chloride plastic bags cannot be used. Contained food, especially not oily food. In addition, polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at high temperature, such as about 50 ℃, which is harmful to human body. Therefore, polyvinyl chloride products are not suitable for food packaging.
