1. The outer packaging of food packaging bags should be labeled in Chinese, including the factory name, production address, product name, and clearly marked with the words "for food use".

2. Food packaging bags should be odorless and odorless when leaving the factory. If there is a special odor, they should not be used on food packaging.

3. Avoid coating packaging materials as much as possible. If a large amount of coated material is used solely to maintain the aesthetics of the packaging, it is completely unnecessary. This is not only because adding coatings increases the difficulty of recycling and reusing packaging bag materials, but also because most coating materials themselves have toxicity. At the same time, the coating process can cause certain environmental pollution, which is not in line with the concept of sustainable development strategy.

Immersion method: immerse the plastic bag in water, and if it is non-toxic, the packaging bag can surface; On the contrary, the packaging bag will not float.

Touch method: Directly touch the plastic bag with your hand. If the packaging bag has a sense of lubrication, it is non-toxic; On the contrary, toxicity.

Flapping method: Lift the packaging bag in the air and pat it vigorously. If a clear sound can be heard, it indicates that the packaging bag is non-toxic; On the contrary, it has toxicity.

Fire burning method: A corner of the packaging bag can be cut off and ignited. If it is easy to burn, it is non-toxic; On the contrary, it has toxicity.

Cleverly utilizing the aforementioned precautions and methods can help you choose food packaging bags correctly in your daily life.
