Vacuum Packaging Machine Achieves The Preservation Effect By Inflating

In fact, the preservation principle of the vacuum packaging machine is not complicated, and the most important part is to remove the oxygen in the packaging.

Just take out the oxygen in the packaging bag and the food, and then seal the packaging to avoid air entering, and no oxidation reaction will occur, thus achieving the effect of preservation.

An important part of the vacuum packaging machine is inflation. Vacuum inflatable packaging not only has the function of deoxidizing and guaranteeing quality, but also can resist pressure, block gas, and preserve freshness, and can effectively maintain the original color and fragrance of food for a long time.

It is worth noting that some foods are not suitable for vacuum packing machine, but must be vacuum inflated. For example, foods that are crunchy and brittle, easy to agglomerate, easy to deform and lose oil, angular or high hardness may puncture the packaging bag.

After the food is inflated and packaged by the vacuum packaging machine, the inflation pressure in the packaging bag is stronger than the pressure outside the packaging bag, which can effectively prevent the food from being broken and deformed, and will never affect the appearance of the packaging bag. The vacuum inflatable packaging of the vacuum packaging machine is filled with carbon dioxide, nitrogen or mixed gas after being vacuumized.

Among them, nitrogen is an inert gas, which plays the role of filling, which can keep the positive pressure in the bag, prevent the air outside the bag from entering the bag, and play a protective role on the food.

Carbon dioxide can dissolve in a variety of fats and water to form carbonic acid, which has an inhibitory effect on mold and spoilage bacteria.
