Food manufacturers, in addition to the safety and environmental protection of food production, also need to use harmless and environmentally friendly packaging bags for packaging when purchasing packaging bags, so how to correctly choose food packaging bags and use food packaging bags? Note the following:

1. The outer packaging of food packaging bags must have Chinese logos, marked with the name of the factory, the address of the factory, and the name of the product, and the words “for food” should be clearly marked, and the product will be accompanied by a product inspection certificate after leaving the factory;

2. Food packaging bags are odorless and odorless when leaving the factory, and packaging bags with special odors cannot be used for food packaging;

3. Colored plastic packaging bags (such as dark red or black currently on the market) cannot be used for food packaging, because such plastic packaging bags are often made of recycled plastic;

4. Try to use materials that are not coated or coated. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used. This not only brings difficulties to the recycling and reuse of materials after the products are scrapped, but most of the coatings themselves are toxic. If people eat these packaged foods, it will cause great harm to people’s bodies. In addition, the coating and plating process also brings great pollution to the environment. For example, the paint volatilizes toxic solvent gas, and the waste liquid and waste residue pollution containing heavy metals such as chromium are generated during electroplating. Therefore, packaging materials that are not coated or plated should be selected as far as possible.
