Polyvinyl alcohol (PVA) biodegradable hydrolyzed film production technology

This product is a biodegradable and hydrolyzed polyvinyl alcohol (PVA) film with higher strength than polyethylene (PE) film and good transparency. Its characteristics, strong water absorption, can be completely degraded in water or soil, no pollution to the environment, the membrane is not static, does not vacuum, good printing performance, good resistance to oil and chemical substances, breathable and oxygen, can play Preservative preservation. Can be used for high-end clothing packaging; can be combined with polyethylene or polypropylene film production of food packaging bags; and paper materials into a gift bag; for anti-static requirements of the packaging, such as the packaging of electronic components. The increasing market demand has great potential. The film has advanced production technology and is the first to be created in China.

The Institute has been engaged in the research and production of unsaturated polyester resin for 30 years; in the 1980s, it began to design large-scale unsaturated polyester engineering and transfer of special technology, and has completed 1,000 tons/year, 3000 tons/year, and 6,000 tons/year. Years of resin engineering.
