Skin vacuum packaging machines and vacuum packaging machines, literally speaking, both involve the process of vacuum extraction. So what are the differences between the two types of machines? This is a common confusion among many users, who are unsure which equipment to choose when making a purchase. Below, we will differentiate between these two types of equipment for you.

1. Different packaging methods. Although both machines are used for vacuum extraction, their packaging methods are entirely different. Vacuum packaging machines typically require placing items into bags, then extracting the air and sealing them. In contrast, skin vacuum packaging machines also extract air but use a film to cover the items, with the base being either a film or a tray. The result of this packaging is that, aside from the area where the item is located, all other parts are smooth. In contrast, vacuum packaging results in wrinkles in other areas.

2. Different consumables used. Vacuum packaging machines use vacuum packaging bags, which are made of composite materials but lack adhesiveness. On the other hand, skin vacuum packaging machines use PE skin film, which has a thickness similar to vacuum packaging bags but possesses a certain level of adhesiveness. After heating, it can adhere well to the surface of the product and then cool to set its shape.

3. Different applicable fields. Skin vacuum packaging is mainly applicable in two major areas: food and workpieces. For food, it must be solid; powders and liquids are not suitable. In contrast, vacuum packaging machines have a much wider range of applications, suitable for solids, liquids, powders, and more. Additionally, vacuum packaging machines can accommodate items of various sizes, whereas food skin packaging machines are more limited in this regard.
