Our lives now advocate food safety, hygiene and health. The focus of food packaging is to extend the shelf life of food and prevent corrosion. So strong packaging is very important. Food spoilage is caused by the growth and reproduction of microorganisms. Oxygen in the air causes oxidative deterioration. The water vapor and carbon dioxide generated by the action of oxidase and peroxidase inside the food can also cause food deterioration. Therefore, it is wise to use vacuum packaging. The choice, he can take away the air inside the food packaging bag and the food, in a vacuum state, isolate the air and inhibit the growth and reproduction of microorganisms.
In addition, there are many foods that are not only vacuum-packaged, but also vacuum-inflated, such as crispy and fragile foods, foods that are easily deformed and oily, foods that are prone to moisture and agglomeration, and those that are angular or have a high hardness that will pierce the packaging bag Vacuum inflatable packaging such as food is filled with single or 2-3 mixed gases such as nitrogen, oxygen, carbon dioxide, etc. after being evacuated. Nitrogen is an inert gas that can protect the packaging. Carbon dioxide is soluble in water or various types. Fat forms carbonic acid, which has the effect of inhibiting the growth and reproduction of mold and spoilage bacteria. Oxygen can inhibit anaerobic bacteria, prevent the oxidation of food, and maintain the freshness of fruits and vegetables. High-energy oxygen can also maintain the bright red color of meat, so vacuum Inflatable packaging also has anti-pressure, gas-barrier, and fresh-keeping effects, and can effectively retain the color, fragrance, taste, shape, and nutrients of the food.
The vacuum packaging machine allows us to eat healthy and safe food, which also means that we must work harder to develop practical, sophisticated and advanced vacuum packaging machines.
