What Is The Impact Of Vacuum Skin Packaging Machine On Shelf Life?

When we choose fresh food, we need to check the freshness of this product. In addition to visual inspection, we also need to check the production date on the outer packaging of fresh food. For fresh food, the packaging type is Modified Atmosphere Packaging Equipment, which has a fresh lock function. This vacuum skin packaging machine can lock the freshness of fresh food for a certain period of time, thereby extending the shelf life of the food. Especially for fresh meat, it can ensure that the meat is fresh, tender and not discolored, and can keep the original color of green vegetables unchanged. However, the shelf life of this fresh food is relatively short, and it can be stored at a temperature of about 0℃, and the shelf life can reach 7-10 years. For most vacuum-packed foods, the shelf life can usually reach less than 180 days. The reason why this kind of food can achieve such a long shelf life is related to the packaging process of its products. After the food is packaged by the vacuum packaging machine, it needs to be placed in a high-temperature pot for anti-virus. The anti-virus food can achieve a very long shelf life. For example, snack foods such as dried beans, chicken feet and beef jerky, as well as sausages, ham, marinated eggs and other products we usually eat, all use this packaging process to extend the shelf life of food. In addition to these two packaging methods, there is also a special kind of food. From the appearance of this kind of food, it is almost impossible to see the existence of the outer packaging. This is mainly because this kind of food uses a highly permeable film when packaging, and the packaging effect of the film being closely connected to the product is achieved by heating the film. This packaging method is vacuum skin packaging. At present, the products used for skin packaging are generally seafood and fresh foods, and the shelf life of these foods is relatively short, which is basically similar to the shelf life of the modified atmosphere vacuum packaging machine mentioned above. When the food is stored at around 0℃, the shelf life can reach about 7-10 days.
