BMSC is a green environmental-protection thermoplastic resin as well as a complete biological degradable material ,which is produced by taking starch as the matrix and applying the melt intercalation plastifying extrusion technique. The material excludes polyolefin material and is featured by high performance cost, natural anti-static property, low-carbon and environmental protection, and others; this material is originated from the renewable resources, and finally degraded under the nature or compost and other specific conditions, and changed to be carbon dioxide, water and other harmless substances. It passes through the qualification certification of EU plastic package material standard (EN13432) on heavy metal and degradable part by Belgium OWS detection organization; obtains bio-based material certification and certificate from German DIN CERTCO detection organization; obtains OK Biobase certification at Belgium VINCOTTE, and three-star (BMSC/VA-50) certificates.
