Composite vacuum bag refers to the composite of two or more films with different barrier properties through a certain process. In this way, the permeable molecules have to pass through several layers of membranes to reach the interior of the package, which is equivalent to prolonging the permeation path, thereby improving the barrier performance. The […]

The comparison of aluminum foil vacuum bags and nylon vacuum bags Vacuum bag has been a popular series of packaging, and more and more products need to be packaged in vacuum bag. Products packaged in vacuum bags have a longer shelf life and safer packaging than ordinary products. There are two kinds of packaging: aluminum foil vacuum bag and nylon vacuum bag, Today we will introduce the difference between the aluminum foil vacuum bag and nylon vacuum bag. 1: Material: The material of aluminum foil vacuum bag is aluminum foil with silver color. Nylon vacuum bag is made of nylon PA/PE.Aluminum foil material can avoid light and with high temperature resistan. It can be used as high temperature cooking bags, aluminum foil material don’t have transparent effect, nylon can only be […]
