Due to the simple process of vacuum packaging bags, the cost can be reduced by 10-20% compared with dry lamination films and other lamination films. Flexible structural design, different structural designs can be used to meet the quality requirements of different products, high strength, co-extruded film has tensile properties during processing, plastic stretching can be improved accordingly, and nylon, metallocene polymer can also be added in the middle. Vinyl plastic material makes it have higher composite strength than general packaging, no delamination, good flexibility, and good heat-sealing performance; the capacity is relatively small, and the co-extruded film can be vacuum shrink-packed, and the volume is relatively close. , Paper packaging incomparable; no binder, no residual solvent pollution, green and environmental protection.
In the choice of packaging bags, which one should you choose? If you choose vacuum packaging bags, what are the reasons? First of all, there is a good "sealing" effect, we know that things, especially food, are particularly afraid of oxygen, because oxygen is an important part of the survival of many organisms, but bacteria are also organisms, and some bacteria can be under the action of oxygen in large quantities Breed, never jeopardize the quality of things like food. However, vacuum packaging bags, as the name implies, should be in a vacuum or near-vacuum state, so they can play a very good "air barrier effect". In fact, vacuum packaging bags can not only play the role of oxygen barrier, but also insulate gases such as carbon dioxide. Second, the use of vacuum packaging bags is safe. The vacuum packaging bag adopts the "green" production concept, no chemicals such as adhesives are added in the production process, and it is a green product. Vacuum packaging bag is a packaging method in which the product is put into the bag, and the air in the bag is sealed and the product is extracted. Some long-distance high-fat foods, such as marinated products, ham, grilled fish, Peking duck, Texas grilled chicken, etc., will easily deteriorate after a long time in the air and oxygen. Vacuum packaging bags, preferably high temperature cooking vacuum packaging bags.
There are many things in our daily life that can easily go bad, such as meat and grains. This situation has led many of these perishable food processing companies to use a variety of methods to preserve the freshness of these foods when producing and storing them. This makes the application. The vacuum packaging bag actually packs the product into a sealed packaging bag, and exhausts the air from the bag through some tools, so that the bag is in a vacuum state. The vacuum bag is a condition that allows the bag to be decompressed for a long time, and the air is thin and low-oxidation environment, so that many microorganisms cannot survive. With the continuous improvement of our living standards, people's quality of various items in life has also undergone considerable changes, and aluminum foil packaging bags are frequently used products in our lives, occupying a considerable weight. Vacuum packaging is a product of packaging technology and plays a vital role in our daily life. The high-temperature sterilized packaging bag not only provides a very safe storage environment for food, but also is safer in the aluminum foil bag itself. In addition to using high-temperature cooking and sterilization technology, it can also provide good protection for foods that cannot be exposed to sunlight, and aluminum foil materials that prevent sunlight reflection. In order to prevent the bag from being punctured, a preservative was added deliberately. Packed in vacuum bags, the umami and color of oily foods can be preserved until they are opened.
