The following points should be paid attention to when choosing packaging bag correctly and using Packaging Bag:
1. The outer packaging of food packaging bag should have a Chinese mark, marked with the name of the factory, the address of the factory, the name of the product, and marked with the words "for food" in the obvious place. After the product leaves the factory, the product inspection certificate is attached.
2. Product packaging bags are odorless and odorless when leaving the factory. Packaging bags with special smells cannot be used for food packaging.
3. Colored plastic packaging bags (dark red or black and other colors currently used in the market) cannot be used for food packaging, because such plastic packaging is often made of recycled plastic.
4. Try to choose materials without coating or coating. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with coating are used. This not only brings difficulties to the recycling and reuse of the materials after the products are scrapped, but also most of the coatings themselves are toxic. If people use these packaged foods, it will cause great Weihai to people's bodies. In addition, the process of coating and plating also brings great pollution to the environment, such as toxic solvent gas generated by coatings, waste liquid containing chromium and other heavy metals produced during electroplating, waste residue pollution and so on. Therefore, packaging materials without coating and coating should be selected as far as possible.
