Self supporting zipper bag manufacturers share tips for identifying toxic food packaging bags
It is common to use plastic bags to package food. However, people often ignore the fact that some plastics are toxic to human body. They can easily pick up a plastic bag and use it to hold food.
PVC plastics are toxic; PVC resins are non-toxic, but when plasticizers dibutyl phthalate or dioctyl phthalate are added in the process of making plastics, they are toxic. In addition, some plastic products have been added with stabilizers, and these stabilizers are mainly lead stearate, which is also toxic. This kind of lead salt is easy to separate out, and once it enters the human body, it will cause accumulated lead poisoning. Therefore, special food bags should be used when loading food, and should not be used indiscriminately. Manufacturers of self-supporting zipper bags remind that attention should be paid to the following points in use:
1. PVC products will precipitate lead when contacting with solvents such as ethanol and ether, so it is not suitable to store alcoholic food with PVC plastic products.
2. When PVC meets oily food, lead will dissolve into food, so it is not suitable for packaging oily food.
3. When the temperature of PVC plastics is higher than 50 ℃, HC will be released slowly, which is harmful to human health.
4. Waste plastic recycling products, due to the complex source of raw materials, inevitably with toxic components, can not be used as food packaging.
Self supporting zipper bag manufacturers introduce that people use polyethylene and polypropylene plastic products without additives in daily food packaging. It is safe to use them as food bags. http://www.dgbpk.com/
