What is the difference between wet and dry bond?
Wet Bond is the laminating process used to laminate two substrates, one of which is porous, such as paper. A foil/paper lamination may be produced by wet bonding. The two substrates are combined prior to passing through the oven, in other words the two substrates are combined before the adhesive is dried. Dry bonding is the laminating process used to laminate two substrates both of which are non-porous (impervious). Film/film and film/foil laminations are examples. The adhesive is applied to one of the substrates and dried in the oven prior to being combined with the second substrate. In other words, the two substrates are combined after the adhesive is dried.
