Vacuum packaging is to put food or other items to be packaged into the packaging bag, draw out the gas inside the bag, reach the predetermined vacuum, and complete the sealing and stamping date process at one time. Due to the food industry's need for freshness preservation, vacuum packaging machines play a leading role in food packaging. It can be said that the emergence of vacuum packaging machines has injected new vitality into the food industry in China and has become a leader in packaging machinery products.
Vacuum packaging machines have entered China with reform and opening up. In recent decades, the vacuum packaging machine industry in China has developed rapidly along with China's economic and technological methods, and the types of vacuum packaging machines have been continuously increasing and functions have become more and more. More often than not, the demand for businesses has also increased.
With the diversification of demand, a variety of vacuum packaging machines have appeared on the market according to demand. The manufacturers of vacuum packaging machines also increased, and the market gradually entered a disorderly state. Many products, consumers can not buy good products, have turned to foreign vacuum packaging machine manufacturers, such as Germany, Britain, the United States, Japan and other countries. This is very unfavorable for the development of the vacuum packaging industry in China.
