The preservation and hygiene of food is a major event in life. How can freshness and freshness be better preserved without losing business? As more and more foods in need of freshness appear in life, freshness-preserving products also appear, such as fresh-keeping films and vacuum packaging bags. Today, the editor will introduce to you the benefits of packing food in vacuum bags.
1. Easy to use. Vacuum packaging bags can be opened easily and safely. When eating, the food in the bag can be opened for consumption, even without heating.
2. Convenient storage and transportation. The vacuum packaging bag is light in material, can be folded, takes up little space, and saves storage costs.
3. Save energy. Vacuum packaging bags are lighter and thinner, and the packaging is sterilized, which consumes 30-40% less energy than iron cans.
4. Long storage time. Vacuum-packed foods do not need to be refrigerated or frozen, have a stable life span, and are comparable to metals for easy long-term use.
5. Maintain the color, aroma, taste and shape of the food. The vacuum bag is relatively thin, and it can reach the sterilization requirement in a short time, as much as possible to preserve the original color, aroma, taste and shape of the food.
In the process of packaging food in vacuum bags, the problems of inflation and sealing are very critical. Some foods are susceptible to spoilage. During production, transportation, and sales, products should be protected from mechanical or external squeezing, and such foods are susceptible to moisture and oxidation. When the packaging machine is working, the solenoid valve and the packaging machine are matched to work, and the air bag is inflated immediately before the horizontal sealing, and the size of the air volume and the length of the inflation time are adjustable. Excessively large amount of inflation may blow up the product and cause pinching; while too small amount of inflation may not achieve the effect of protecting the product.
