FAQ

What material are food vacuum bags usually made of?

Vacuum food bags are usually made of polyethylene composite nylon, and cooked foods are usually made of pure aluminium.


Food vacuum bags are mainly conducive to food storage and preservation. Inhibits the reproduction of microorganisms such as bacteria. For some soft articles, the volume can be reduced by vacuum packaging. Thus, the packaged articles can achieve the characteristics of "four prevention, two provinces and one quality assurance": moisture proof, mildew proof, pollution proof, oxidation proof, volume saving, freight saving, and prolonged storage period. In the food industry, vacuum packaged food is very common. Various kinds of cooked products such as chicken leg, ham, sausage and so on; pickled products such as various pickles and various kinds of soybean products, preserved fruits and other foods that need to be kept fresh are increasingly packaged in vacuum. The shelf life of vacuum packaged food is long, which greatly prolongs the shelf life of food.


What is the harm of unqualified food vacuum bags? Unqualified food vacuum bags will affect the quality of food such as color, aroma and taste, which is not conducive to food marketing. Unqualified food vacuum bags can spoil the food, just like steamed rice and steamed vegetables. It's easy to imagine what effects they have on the body. And unqualified food vacuum bags produce toxic substances to contaminate food, causing serious damage to the body of consumers. Therefore, food vacuum bags with poor quality are very harmful.
