Polyvinyl Alcohol Glue(PVA synthetic glue): It is also called white glue, a kind of chemical synthetic glue, which is an important glue type of the current stamp adhesive. It’s made from the reaction of polyethylene and aldehyde compounds. The colloid is pale and thin, with strong adhesion and strong moisture resistance, and it is widely used in various countries.
