Scope This document specifies the detection method for the determination of polybutylene terephthalate-butylene adipate (PBAT), polylactic acid (PLA), starch, inorganic fillers and other components in starch-based biodegradable plastics using conventional physical and chemical techniques. . This document applies to starch-based biodegradable plastic particles and products with PBAT, PLA, starch and inorganic fillers as the main components. Note: If this method has been previously verified to be applicable to known starch-based biodegradable plastics containing other biodegradable components, the scope of application of this method can be expanded to the analysis of other starch-based biodegradable plastics other than those specified in this method. 2 Normative reference documents 3 Principles 4 Reagents and materials 5 Instruments and equipment 6 Sample preparation 7 Experimental steps 8 Precision 9 Test report
