PVA environment-friendly adhesives began to be used in packaging and other industries in the United States during the Second World War. At that time, PVA was widely used as a adhesive for waterproof V-shaped plate liner boxes, which could drift ashore from cargo ships. Since then, PVA has been firmly established in the relevant developing synthetic chamber adhesives market, such as packaging, paper conversion, furniture, book paste, envelopes, etc.
In some adhesive formulations, PVA acts as a protective colloid, emulsifier, thickener and film forming agent. It can promote the combination of insoluble solvents, plasticizers, paraffins and oils, and improve adhesion and tensile strength.
