GB/T 29646-2013Modified biodegradable polyester used for blown film (English PDF)

1 Scope

This standard specifies the blown film with the modified polyester biodegradable plastics terms and definitions, requirements, test methods, inspection rules, marking

Chi, packaging, transportation and storage.

This standard applies to the one or more have biodegradability of plastic-modified polyester resin prepared via can be used to blow

Bio-degradable plastic film (referred to as biodegradable plastics). Common polyester resin mainly polylactic acid and alpha- hydroxy alkyl esters, poly

Butylene succinate, aliphatic aromatic copolyesters and the like.
