GB/T 38082-2019Biodegradable plastic shopping bags (English PDF)

Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This Standard specifies the terms and definitions, requirements, test methods, inspection rules, packaging, transportation, and storage of biodegradable plastic shopping bags.

This Standard applies to plastic shopping bags made from films produced primarily from biodegradable plastic resins and processed through bag-making processes such as heat sealing or bonding, as well as to shopping bags made from biodegradable plastics combined with other materials.

This Standard does not apply to biodegradable plastic bags that are used solely for packaging and not for carrying, such as biodegradable roll bags (also known as tear bags or perforated bags).
