How to identify the toxicity of plastic bags

Plastic bags are widely used in our daily life especially in food packaging. It is usually made of PE (in general, it is non-toxic) and PVC (in general, it is toxic). So that it is very important to identify the toxic plastic bags.

Here are three simple ways to classify them.
1) Touch: non-toxic plastic bags usually milky white or transparent and the surface is smooth; toxic plastic bags often have different colors (such as yellow, red and black) and the surface is rough.

2) Shake: strongly shake the plastic bag, if it sounds clear and melodious, it is a non-toxic bag, or else it is a toxic bag.

3) Burn: a nontoxic plastic bag is flammable; the dripping of products of plastic bag’s combustion is similar with candle’s combustion and the smelt is also similar with candle. A toxic plastic bag is uninflammable; even though it is lit, the fire can be extinguished easily; if it softens, you can pull effect of filamentous.

These are not accurate identification ways to distinguish nontoxic plastic bags from noxious plastic bags. Accurate identification should performed by professional testing organizations.
