GB/T 33897-2017
Biopolyester—Polyhydroxyalkanoates(PHA) blowing film

This standard specifies the product specifications for films produced using polyhydroxyalkanoates (PHA) as raw materials through the blow molding process. It comprehensively outlines the product requirements, testing methods, and inspection rules for the films. To assess their quality, the standard references several fundamental testing methods, with key detection instruments involved including a contact thickness gauge for measuring thickness deviation, an intelligent electronic tensile testing machine for evaluating tensile strength and right-angle tear strength, and a light transmittance and haze meter for testing light transmittance and haze. This standard provides a unified technical basis for the production and quality control of this type of biodegradable bio-based film.
