The special top film tightly wraps the product, but without pressure, so it will not change the products' shape or decoration. Therefore, even sharp or hard parts of the product, such as bones or shells, can be perfectly packaged by vacuum skin packaging machine without breaking. Products packaged by vacuum skin packaging machine can be displayed vertically, horizontally, or even suspended because the top film firmly holds the contents of the package and it is completely sealed, preventing any liquid leakage from the product. The further advantage of vacuum skin pack is to extend the shelf life and maintain the taste of the product.
