Scope
This standard specifies the terms and definitions, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of modified polyester biodegradable plastics for blown film applications.
This standard applies to biodegradable plastics (referred to as biodegradable plastics) that can be used for blown film applications and are prepared by plastic modification of one or more polyester resins with biodegradable capabilities. Common polyester resins include polylactic acid, polyα-hydroxyalkanoate, butylene succinate, and aliphatic-aromatic copolyester, etc.
