click:333 time:2022-10-14 edit:Hua Di's editor

Nowadays, many foods are using vacuum packaging bags to extend the shelf life of food fresh-keeping boxes. Therefore, the impact of food vacuum bags on people’s lives is growing, and its appearance has a great relationship with our health.


Therefore, when using food vacuum packaging bags, we must pay special attention to the following precautions:


1. The outer package of the food vacuum packaging bag must be marked in Chinese with the name of the factory, the address of the factory, the name of the product, and the word “for food” in a conspicuous position. The product is attached with the product inspection certificate after leaving the factory. This kind of food vacuum packaging bag is relatively safe.


2. Color vacuum packaging bags (such as dark red or black on the market at present) cannot be used for food packaging, because such vacuum packaging bags are often made of recycled plastic.


3. Food vacuum packaging bags shall be free of peculiar smell when leaving the factory. Food vacuum packaging bags with special smell cannot be used as food packaging bags.


4. Try to choose uncoated or uncoated food vacuum packaging bags. In modern packaging design, in order to make the packaging more beautiful and corrosion resistant, a large number of coated materials are used, which not only makes it difficult to recycle and reuse the materials after the products are scrapped, but also most of the coatings themselves are toxic. If people eat the food packaged in these food bags, it will cause great harm to the human body. In addition, the coating process also brings great pollution to the environment. For example, the coating will volatilize toxic solvent gas, and electroplating will produce waste liquid and waste residue containing chromium and other heavy metals. Therefore, food vacuum packaging bags without coating or coating should be selected as far as possible.


The above is the explanation of the precautions for using food vacuum packaging bags. Do you understand it after reading it? I hope it will be helpful to you.
