Vacuum Packaging Machine For Fragile And Deformable Products

People often see some snack bags bulging in supermarkets, which is the effect of being packaged and inflated by a plastic packaging machine. In order to avoid damage to goods like brittle and fragile food, easy caking food, easy to deform and take oil food, sharp edges and corners or high hardness that will pierce the plastic packaging bag, a vacuum inflatable plastic packaging machine was invented. Inflation is an important link in vacuum packaging machine.

The main function of vacuum packaging machine is not only the oxygen removal and quality assurance function of vacuum packaging, but also the functions of compression, gas resistance and preservation, which can more effectively maintain the original color, aroma, taste, shape and nutritional value of food for a long time. In addition, many foods should not be packaged by vacuum packaging machine, but must be packaged by vacuum inflatable plastic packaging machine. Such as crisp and fragile food, easy caking food, easily deformed and oily food, food with sharp edges and corners or high hardness that will pierce the packaging bag, etc.

After the food is vacuum inflated and packaged by the food vacuum packaging machine, the inflation pressure in the packaging bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure and does not affect the appearance of the packaging bag and printing decoration.

The principle of vacuum packaging machine and plastic packaging machine is to fill nitrogen, carbon dioxide, oxygen single gas or a mixture of 2-3 gases after vacuumizing. Nitrogen is an inert gas, which plays the role of filling to maintain positive pressure in the bag, so as to prevent the air outside the bag from entering the bag and protect the food. Oxidized carbon gas can be dissolved in various fats or water to form carbonic acid with weak acidity and inhibit the activities of molds, spoilage bacteria and other microorganisms. Oxygen can inhibit the growth and reproduction of anaerobic bacteria and maintain the freshness and color of fruits and vegetables. In addition, luggage wrapping machine and plastic packaging machine look beautiful, and their use effects also have their own advantages.
