What Is The Importance Of Vacuum Skin Packaging Machine For The Food Industry

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. Therefore, sturdy packaging is very important. The decay and deterioration of food are caused by the growth and reproduction of microorganisms. Oxygen in the air can cause oxidation and deterioration. Water vapor and carbon dioxide produced by the action of oxidase and peroxidase in food can also cause food deterioration.

Therefore, Semi Automatic Tray Sealer is a wise choice. It can remove the air inside the food packaging bag and the food, and isolate the air to inhibit the growth and reproduction of microorganisms under vacuum. In addition, many foods are not only vacuum packed, but also vacuum inflated, such as crispy foods, foods that are easy to deform and lose oil, foods that are prone to moisture and agglomeration, foods with edges or high hardness, which will pierce the packaging bag.

Vacuum inflatable packaging is to evacuate a single or 2-3 mixed gases such as nitrogen, oxygen, and carbon dioxide and then flush them. Nitrogen is an inert gas that can protect the packaging, and carbon dioxide can be dissolved in water or various fats to form carbonic acid, which can inhibit the growth and reproduction of mold and spoilage bacteria. Oxygen can inhibit anaerobic bacteria, prevent food oxidation, and maintain the freshness of fruits and vegetables. High-energy oxygen can also keep meat bright red. Therefore, vacuum packaging also has the functions of compression resistance, gas resistance, and freshness preservation, which can effectively preserve the color, aroma, taste, shape, and nutrition of food.
