Description

Food vacuum packaging bag with one-way exhaust valve Technical Field The utility model relates to the technical field of vacuum packaging bags, in particular to a food vacuum packaging bag with a one-way exhaust valve. Background The packaging bag is used for packaging various articles, so that the articles are convenient to transport and easy to store in the production and circulation process, and is widely used in daily life and industrial production, and various types of the articles are various, such as a vest bag, a straight tube bag, a three-dimensional bag, a square bottom bag, a sealing bag, an adhesive tape bag, a special-shaped bag and the like, wherein the vacuum packaging bag is used as a novel packaging bag, and is widely used for sealing packaging various foods. However, when the conventional vacuum packaging bag for food is connected to an air pump, there is a general problem in that the sealing is poor. Because seal structure design is simple coarse, and the air suction nozzle is difficult to closely laminate with wrapping bag junction, and the air leaks from the gap easily, this not only leads to the extraction inefficiency, consumes a large amount of time and energy, is difficult to reach ideal vacuum moreover for the food can't obtain good fresh-keeping environment, is very easy to deteriorate because of oxidation, wet and microorganism erosion, influences the quality of food.
