The working principle of the vacuum packaging machine is to put food into the packaging bag, extract the air from the packaging bag, and complete the process of sealing. my country's vacuum packaging technology was developed in the early 1980s. With the promotion and promotion of small packaging With the development of supermarkets, its scope of application is becoming wider and wider, and some will gradually replace hard packaging, and the prospects are very good.

The characteristics of packaging articles using vacuum packaging machines are as follows: First, part of the air (oxygen) in the packaging is eliminated, which can effectively prevent food from spoiling and spoiling. Second, the use of packaging materials with excellent barrier properties (air tightness) and Strict sealing technology and requirements can effectively prevent the exchange of items in the package, which can avoid weight loss, loss of taste, and prevent secondary pollution. Third, the gas inside the vacuum packaging container has been eliminated, which has accelerated the conduction of heat. It can improve the sterilization efficiency and avoid the packaging breakage due to the expansion of gas during heat sterilization.

In addition, the inflatable packaging items of the vacuum packaging machine also have the functions of pressure resistance, gas barrier, and preservation, which can more effectively maintain the original color, fragrance, taste, shape and nutritional value of the food for a long time.

Now in the food industry, vacuum packaging applications are very common. Various cooked products such as chicken legs, ham, sausages, grilled fish fillets, beef jerky, etc.; preserved products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh are increasingly being vacuum-packaged.
