T/GDPIA 53-2022 Method for the Analysis of the Composition of Starch-Based Biodegradable Plastics
T/GDPIA 53-2022 The method for analyzing the composition of starch-based biodegradable plastics
Basic Information
Scope
Scope: This document specifies the detection methods for determining the components of starch-based biodegradable plastics, including polybutylene terephthalate (PBAT), polylactic acid (PLA), starch, and inorganic fillers, using conventional physical and chemical techniques. This document is applicable to starch-based biodegradable plastic particles and products primarily composed of PBAT, PLA, starch, and inorganic fillers. Note: If it has been preliminarily verified that this method is suitable for starch-based biodegradable plastics containing other biodegradable components, the scope of application of this method can be extended to the analysis of other starch-based biodegradable plastics beyond those specified in this document.
