How to correctly select and use food packaging bags

　　In addition to the safety, environmental protection and harmlessness of food production, food manufacturers also need to use environmentally friendly packaging bags for packaging when purchasing packaging bags. So how to correctly select food packaging bags and use food packaging bags should pay attention to the following points:

　　1. The outer package of the food packaging bag shall be marked with a Chinese logo, indicating the name, address and product name of the manufacturer, and the word "for food" shall be marked in a conspicuous place. The product shall be attached with a product inspection certificate after leaving the factory;

　　2. When the food packaging bag leaves the factory, it is odorless and odorless, and the packaging bag with special smell 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 bags are often made of recycled plastic;

　　4. Try to select materials without coating or plating. 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 makes it difficult to recycle and reuse the discarded materials, but also makes most of the coatings themselves toxic. If people eat these packaged foods, they will do great harm to their health. In addition, the coating and plating process also brings great pollution to the environment. Such as volatile toxic solvent gas of paint, waste liquid and residue pollution of chromium and other heavy metals during electroplating. Therefore, packaging materials without coating shall be selected as far as possible.
