Food vacuum skin packaging is the process of vacuum sealing products between a transparent vacuum film and a chassis in a vacuum state. It can maintain the color, aroma, and freshness of the product, and has the dual effects of three-dimensional display in body packaging and vacuum preservation protection. Its characteristics are as follows: vacuum fully sealed packaging can maintain the natural freshness, aroma, color, and juice flavor of the product. Using high barrier vacuum packaging film can block oxygen, inhibit the growth of aerobic bacteria in low temperature environments, preserve the product for a longer period of time, and protect its natural color. It can prevent the formation of ice crystals during refrigeration and prevent the surface of the product from drying and cracking due to freezing burns. It can be used as a combination packaging for multiple products. Consumers can partially open the packaging for consumption, and then put the remaining products in the packaging back into the refrigerator for further refrigeration for future consumption, which is hygienic and convenient.
