Polyvinyl Alcohol(PVA) is widely used environment-friendly material. After biodegradation & hydrolysis, it only generate water and carbon dioxide. It is of biodegradability, barrier resistance, antistativity, oil resistivity, good translucency and etc. But PVA cannot be thermoplastic processed through traditional method which limited its application. After many years of efforts, we have successfully developed the polyvinyl alcohol resin particles that can be melting-thermoplastic processing. It is called thermoplastic-polyvinyl alcohol(P-PVA, P-PVOH).
