Vacuum packaging machines' working principle is to vacuum the packaging bag, then seal it to form a vacuum status in the bag, so that the packaged items can achieve oxygen insulation, freshness, moisture, mildew, rust, corrosion, insect, pollution, etc. The purpose is to effectively extend the shelf life, preservation period and facilitate storage and transportation. The equipment is suitable for various plastic composite film or aluminum foil composite film bags.
Vacuum packaging machine is widely used in:
Grain (eg: corn, rice, millet, soybean);
Vegetables (eg: shiitake mushrooms, fungus, sauerkraut, garlic, green onions);
Meat (eg: beef, pork, chicken, duck, lamb, fish, seafood);
Candied fruit, dried fruit, dried mango, banana slices, dried dragon fruit; Chinese medicinal materials (eg: medium berry, astragalus);
Medical equipment (medical surgical masks, masks, scalpels, medical gloves, surgical gowns);
Powder objects (flour, bean powder, coffee powder, yeast powder, starch, garlic powder, corn powder); vacuum packaging of some liquids.
Due to the high vacuum in the bag, it can effectively prevent the corruption and deterioration of the products caused by the oxidation of lipids and the reproduction of aerobic bacteria, and achieve the functions of quality preservation, freshness, taste and color preservation, and extend the storage period of the product. For some soft items, the packaging volume is reduced after vacuum packaging, which is convenient for transportation and storage.
