1. The first thing to see is whether the appearance of the plastic bag has the "food" logo. Usually, this sign should be on the front of the packaging bag, at a conspicuous position. Secondly, it depends on the color. Generally speaking, most plastic bags with color use recycled materials from waste plastics, which cannot be used to contain food. For example, some food markets use black plastic bags to hold fish, shrimp and other aquatic products or meat, which were originally used to hold garbage, and consumers should avoid using them. Finally, it depends on whether the plastic bag has impurities. Put the plastic bag in the sun or light to see if there are black spots and holes. The plastic bag with impurities must be made of waste plastic.
2. Smell the plastic bag to see if it smells and if it makes people feel sick. Qualified plastic bags should be odorless, while unqualified plastic bags will have various tastes due to the use of additives.
3. The qualified plastic bag has a certain strength and will not be broken once torn; The unqualified plastic bags are often of poor strength and easy to crack due to impurities.
