There are many types of vacuum bags, and the main categories are industrial packaging and food packaging. The product standard required for food vacuum bags is significantly higher than that of ordinary industrial products. What should be paid attention to when selecting the food vacuum bag correctly?
1. The food packaging bag for food should have a Chinese logo, label the name of the factory, the address of the factory, the name of the product, and indicate the word "food" in the obvious place. The product inspection certificate is attached to the product after leaving the factory.
2. The food packaging bag for food is no smell or smell, and the food packaging bag with special smell cannot be used for food packaging.
3. Colored food packaging bags (dark red or black colors currently on the market) cannot be used for food packaging. Because these food packaging bags are often made from 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 amount of material with plating is used. This not only makes it difficult to recycle and reuse the 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 brought great pollution to the environment. For example, if the paint volatizes toxic solvent gas, it will produce waste liquid containing heavy metals such as chromium and waste residue pollution during electroplating. Therefore, packaging materials that are not coated or coated should be used as much as possible.
5. It is best to buy food in large shopping malls, and don't go to street stalls to buy.
6. Because food packaging bags are not easily degraded, they cause environmental pollution. Therefore, when purchasing food, it is best to use green packaging materials. Paper is currently the most widely used green packaging material. Therefore, when purchasing food, it is best to choose the original paper packaging, biodegradable plastic can also be used
