In China, mask bags are usually made of two kinds of plastic films: one is made of polyethylene, polypropylene and melamine, which is non-toxic, can be used as a mask bag, and the other is made of PVC bags. It is toxic and cannot be used as a facial mask bag. There is also a common recycled plastic bag made of recycled plastic products, which can not be used as a mask bag. This is because many additives, such as stabilizers and plasticizers, need to be added in the production process of PVC plastic bags and recycled plastic bags. Some toxic substances in these additives will decompose into polymerized monomers when they are stored at high temperature or stored for a long time, especially when they come into contact with greasy food, which will cause great harm to human health.
So how do we identify toxic and non-toxic facial mask bags?
1. Look. The non-toxic plastic bags are white, transparent or slightly transparent with uniform texture; the toxic plastic bags are colored or white, but the transparency is poor and turbid, and the plastic surface is stretched unevenly with small particles.
2. Listen. When you shake the plastic bag with your hands, the crisp sound of the loud clam shows that it is a non-toxic plastic bag, while the sound is small and stuffy is the toxic facial mask packaging bag.
3. Touch. Touch the surface of the plastic bag with your hand. It is very smooth and nontoxic; the sticky, astringent and waxy feeling is poisonous.
4. Nose smell. Nontoxic mask bags are tasteless; toxic or odorless are poisonous.
5. Submergence test. Put the mask bag into the water, press it to the bottom with your hands, wait a moment, and the surface is a non-toxic mask packaging bag, which is a toxic facial mask packaging bag.
