Vacuum packaging machines can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum level. It can also be filled with nitrogen or other mixed gas, and then complete the sealing process.
Vacuum packaging machines are often used in the food industry. Vacuum packaging machines use plastic or plastic aluminum foil films as packaging materials to vacuum pack liquids, solids, fruits, chemicals, medicinal materials, electronic components, etc. The vacuum-packed items can prevent Oxidation, mildew, moth-eaten, rot, moisture, prolong the shelf life.
In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum deoxygenation is to prevent food oxidation. Because oily food contains a large amount of unsaturated fatty acids, it is oxidized by the action of oxygen, which makes the food taste and deteriorate. Loss of vitamins A and C, and unstable substances in food coloring are affected by oxygen, darkening the color. Therefore, deoxygenation can effectively prevent food spoilage.
Vacuum packaging machines are also especially suitable for tea, food, medicine, shops, research institutions and other industries. They have the advantages of beautiful appearance, compact structure, high efficiency, easy operation, and a seat wheel at the bottom, which is convenient to move.
