There are many types of plastic bags, and a commonly used one is called a vest bag As the name suggests, this bag looks cute and has high handles on both sides, just like a vest. Vest bags can be said to be one of the commonly used plastic bags. They are thicker than ordinary lightweight hard bags and have a stronger load-bearing capacity. Vest bags are commonly used to make supermarket, medium, and small-sized shopping bags. T-shirt bags are not easily torn because they are thicker and are usually not used once but repeatedly used to carry items.
vest bag It is determined by its appearance. In addition to the prominent high handles on both sides of the vest bag, there is also a small round hole in the middle of the middle handle. The purpose is to facilitate the use of ropes to stack the bags and drag them when easy to use, and the position of the material of such a series of small holes is much thinner than the material of the bag itself. Usually vest bag weigh some heavier items, such as fruits and vegetables, while disposable lightweight plastic bags are not suitable for heavier items, so vest bags should be used.
vest bag Rarely touted, supermarkets usually print the supermarket's name, address, phone number, and service slogan on plastic vest bags to promote communication among consumers and expand their reputation and brand awareness. Almost all different enterprise custom styles have their own exclusive vest bags, which not only serve consumers but also showcase product features, have unique brand awareness, and indeed have multiple uses.
vest bag Not only shows the consumer's life wisdom but also meets people's convenient and fast psychological needs in production and life. Although the bag is small, its load-bearing function is obvious, which is also the reason for its popularity in daily life.
vest bag The main function is to remove oxygen and prevent food spoilage. The principle is relatively simple: food spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen to survive. In vacuum packaging, this principle is used to remove oxygen from the packaging bag and food cells, thereby depriving microorganisms of their living environment.
Experiments show that when vest bag the oxygen concentration is ≤1%, the growth and reproduction rate of microorganisms will drop sharply. When the vest bag oxygen concentration is ≤0.5%, most microorganisms will stop reproducing.
In addition to controlling the growth and reproduction of microorganisms, vacuum deoxygenation is another important function to prevent food oxidation. Because oils contain a large amount of unsaturated fatty acids, they will be oxidized under the action of oxygen, causing the food to produce an unpleasant odor and deteriorate. In addition, oxidation will also lead to the loss of vitamins A and C, and unstable substances in edible pigments will be affected by oxygen, causing the color to darken. Therefore, deoxygenation can effectively prevent food spoilage.
When using vest bag the following points should be noted:
Do not scratch with sharp objects. If there are hard objects such as buttons and zippers in the stored items, fold them and put them in the storage bag. Clothes, quilts, and other items should be placed in the bag as much as possible, at least 3-5 cm away from the sealed zipper, and do not forcefully stuff large items into the bag. To ensure the hygiene of the sealed zipper parts, if fibers and dust enter, the sealing function will be reduced. It is recommended to clean the vest bag zipper after cleaning with water-soaked gauze.
Use the threaded interface of the air pump and rotary pump, and pay attention to the vest bag before and after inflation. The red rubber seal on the air intake ensures that there is no air leakage at the interface. Usually, a large vest bag needs to be pumped for 3 to 5 minutes. Usually, three to five hundred pieces are needed to achieve a flat appearance. After drawing, check the vest bag seal again to ensure that it is sealed.
