Identification of toxic food packaging

it is common to use plastic to package food in daily life, but sometimes people often ignore the fact that some plastics are toxic. They just pick up a plastic bag and use it to contain food, unaware that it is harmful to human health. There are toxic varieties in our commonly used plastic bags. For example, the PVC plastic liquidation test-bed is a toxic variety; PVC resin is non-toxic, but the plasticizer di-n-butyl phthalate or di-n-butyl phthalate is added in the process of making plastics, so that we have established a long-term cooperative relationship with many foreign customers, and di octyl phthalate is toxic. In addition, some plastic products are added with stabilizers, and these stabilizers are mainly lead stearate, which is also toxic. This kind of lead salt is very easy to precipitate. Once it enters the human body, it will cause accumulated lead poisoning. Therefore, special food bags should be used when loading food, and they must not be used indiscriminately.
