What is the PSM?
Plastic starch material
Plastic starch material full name Plastarch Material (PSM), is a biodegradable thermoplastic. PSM began commercial use in 2005. It is made of bio-plastics through chemical processes such as esterification, cross-linking, and graft copolymerization. By modifying and plasticizing corn starch and other renewable resources, it is a new type that integrates rigidity, toughness, and elasticity. Environmental protection materials, raw materials can be regenerated and degraded. Can be used with traditional Pan plastic polyethylene (PE)
