What should be paid attention to in vacuum packaging bags
January 9, 2023
Points to note when using vacuum packaging bags
1, The outer packaging of the vacuum packaging bag must have a Chinese logo, label the factory name, factory address, product name, and indicate it in an obvious place”for food”typeface. After the products leave the factory, there are product inspection certificates attached. This kind of food vacuum packaging bag is relatively safe.
21. Colored vacuum packaging bags cannot be used for food packaging, and the dark red or black ones currently on the market. Because such vacuum packaging bags are often made of recycled plastic. Not very safe and hygienic.
31. Vacuum packaging bags have no smell or smell when they leave the factory. Food vacuum packaging bags with special smell cannot be used as food packaging bags. What’s more, the smelly ones may be recycled and remanufactured. Who knows what was packed before, especially food packaging should pay more attention to this point.
4Try to choose food vacuum packaging bags without coating or plating. Because many merchants in modern packaging design use a large number of materials with coatings in order to make the packaging more beautiful and corrosion-resistant. This not only brings difficulties to the recycling and reuse of 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 people’s health.In addition, the coating and plating process has also brought great pollution to the environment. For example, the paint volatilizes toxic solvent gas, and the waste liquid and waste residue pollution containing heavy metals such as chromium are produced during electroplating. Therefore, vacuum packaging bags without coating and plating should be used as much as possible.The above are written in the requirements for installing food vacuum packaging bags. If it is not for food, the requirements can be relaxed a little.
