The automatic vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be filled with nitrogen or other mixed gas, and then the sealing process can be completed. The automatic vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation.
The vacuum degree of food containers packed by vacuum packaging technology is usually 600-1333pa. Therefore, vacuum packaging is also called vacuum packaging or exhaust packaging.
China's automatic vacuum packaging technology developed in the early 1980s, while the vacuum inflatable packaging technology began to be used in a small amount in the early 1990s. With the promotion of small packaging and the development of supermarkets, its scope of application is more and more extensive, and some will gradually replace the hard packaging, with a very promising prospect.
Vertical automatic vacuum packaging machine uses plastic or plastic aluminum foil film as packaging material to package materials, which is suitable for food, grain, tea, pickle, medicine, electronic components and other products. The price is relatively cheap, suitable for department stores, supermarkets, food stores, stores, pharmacies, research institutions and other industries.
Advantages: simple operation, can be packed together with the outer packaging (such as barrels, boxes).
