Polyvinyl alcohol (PVA) resin is a kind of heavy polymer. It is usually a white or slight yellow floccules, flake, granular or powdery in appearance. PVA is non-toxic, insipid and non-polluting. PVA is a kind of water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties
