GB/T 44824-2024 "Biaxially stretched polylactic acid film" stipulates the product classification, technical requirements, inspection rules and labels, Encasement, transportation and storage of biaxially stretched polylactic acid film. The standard is applicable to ordinary and heat-sealed films made of polylactic acid Resin as the main raw material and by flat film biaxial stretching process. The standard describes in detail the technical requirements of the film's Appearance, dimensional deviation, biological degradation, and specifies the tensile strength, thermal cissing rate, light transmitance, coefficient of friction, wetting tension and other key performance test methods. It also includes factory inspection, type inspection requirements, and sampling and determination rules to ensure product mass stability and compliance with biodegradation standards. This standard applies to relevant production and quality control departments to help ensure product performance and environment friendliness in practical applications.
