The performance of food vacuum packaging materials directly affects the storage life and taste changes of food. Choosing the right packaging materials is the key to the success of vacuum packaging. So which material is good for food composite vacuum packaging bags?

The better material now is nylon+polyethylene (PA+PE), and the vacuum packaging bags made of PA+PE composite material are made of a new type of plastic composed of nylon material and plastic. This material has a low probability of air leakage in vacuum packaging bags, good flexibility, wear resistance, and can withstand low temperatures. Usually suitable for packaging frozen foods, high-temperature foods, foods with bone spurs, etc.

Because the cost of vacuum packaging bags made of PA+PE composite material is relatively high, some dealers have falsified them. Jinde Packaging will teach you how to identify them. The general identification methods include: PA+PE can slowly burn during the combustion test, with a bright flame, blue at the bottom and yellow at the top, continuous burning after melting droplets, and smokeless melting droplets with the smell of candle blowing out and burning wool.
