The vacuum packaging machine can automatically extract air from the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. Nitrogen or other mixed gases can also be refilled and the sealing process can be completed. Vacuum packaging machines are often used in the food industry because after vacuum packaging, food can resist oxidation and achieve long-term preservation.

Vacuum packaging technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used for vacuum packaging, and since then, vacuum packaging has developed rapidly.
China's vacuum packaging technology was developed in the early 1980s, while vacuum inflatable packaging technology began to be used in small quantities in the early 1990s. With the promotion of small packaging and the development of supermarkets, its applicability has become increasingly widespread, and some will gradually replace hard packaging, with a very promising future.
Food vacuum packaging machine is used for vacuum packaging of sausages, meat products, biscuits and other foods. Packaged food can prevent mold growth, maintain quality and freshness, and extend the storage period of the product. Simply press the vacuum cover to automatically complete vacuuming and sealing.
