摘　　要：为研究生物降解塑料购物袋在生物降解性能、印刷质量、物理力学性能等方面存在的质量安全风险,参照现行国家标准要求,项目研究团队对10批次市售生物降解塑料购物袋产品的生物分解率、厚度及偏差、印刷剥离率、跌落试验、封合强度、提吊试验、落镖冲击等指标进行了检测。经风险评估,部分生物降解塑料购物袋厚度均一性较差,印刷质量不高,物理力学性能不佳,存在产品质量安全隐患。In order to study the safety risk assessment of biodegradable plastic shopping bags,the biodegradation rate,thickness and deviation,printing peel rate,drop test,sealing strength,lifting test,falling dart impact were tested for 10 samples.The results showed that some biodegradable plastic shopping bags have poor thickness uniformity,poor printing quality and poor physical and mechanical properties,there are hidden risks of product quality and safety.
