The main features of food vacuum packaging machine Apr 23, 2018

The main role of food vacuum packaging machine in addition to the vacuum packaging has the function of oxygen removal and quality, there are mainly pressure, gas barrier, preservation and other effects; In addition, many foods are not suitable for vacuum packaging and must use vacuum inflatable packaging.

After the food is vacuum-packed, the inflation pressure in the bag is greater than the atmospheric pressure outside the bag, which can effectively prevent the food from crushing and deforming without affecting the appearance of the bag and printing and packaging. After being packed in vacuum, electronic and semi-conductor products can be protected against static electricity, oxidation, and moisture, so that they can be stored and used for a long period of time without being damaged due to external reasons. Clothing, clothing, and quilt can also be vacuum-packed, which will greatly reduce the storage space, and it will be free from damage such as insects, moisture, and mildew.

The vacuum packaging machine is filled with nitrogen, carbon dioxide, oxygen single gas or a mixture of two or three gases after vacuum. Its nitrogen is an inert gas, which acts as a filling to maintain a positive pressure inside the bag to prevent air outside the bag from entering the bag. Its oxygen inhibits the growth and reproduction of anaerobic bacteria, maintains the freshness and color of fruits and vegetables, and high concentrations of oxygen. Fresh meat can be kept bright red.
