目前，国内的食品包装袋一般可分为单膜袋和复合薄膜包装袋两大类。其主要执行标准有：GB/T4456-1996《包装用聚乙烯吹塑薄膜》、GB12025-1989《高密度聚乙烯吹塑薄膜》、QB/T2461-1999《包装用降解聚乙烯薄膜》、GB9687-1988《食品包装用聚乙烯成型品卫生标准》、GB9688-1988《食品包装用聚丙烯成型品卫生标准》等。

食品包装袋检验项目

按照单膜袋和复合膜袋两种不同的材质，需分别进行不同的检验项目。

单膜袋检验项目主要分为三大类：一、外观不得有对使用有碍的气泡、穿孔、水纹、暴筋、塑化不良、鱼眼僵块等疵病；二、规格、宽度、长度、厚度偏差均应有规定的范围内；三、物理机械性能包括拉伸强度、断裂伸长率。

复合膜袋检验项目主要分为四大类：一、外观应平整，无划伤、烫伤、气泡、破油和折皱，热封平整、无虚封，薄膜不得有裂纹；二、孔隙和复合层分离。无杂质、异物和油渍等污染；三、袋装浸泡液，不得有异味、异臭、浑浊和脱色现象；四、包括拉伸强度、断裂伸长率，气体透过量、耐油度指标、耐热、耐寒以及袋的封口剥离力、袋的耐压和耐跌落性等指标。
