We need to use and come into contact with various packaging bags in our daily life, but many people don’t know what to pay attention to when using packaging bags. Here are some things to pay attention to when using self-supporting zipper bags:
1, The outer packaging must have a Chinese logo, marked with the factory name, factory address and product name, and marked in an obvious place”for food”All products must have a product inspection certificate after leaving the factory. This kind of food self-supporting zipper bag is relatively safe.
2. The colored ones cannot be used for food packaging, and the dark red or black used in the market is currently used. Because these are often made of recycled plastic. Not very safe and hygienic. Be careful.
3. There is no peculiar smell and no peculiar smell when it leaves the factory. Food self-supporting zipper bags with special smell cannot be used as food packaging bags. In addition, the smelly ones may be recycled and remanufactured. Who knows what was packed before, especially the food packaging should pay more attention.
