目前，國內(nèi)的食品包裝袋一般可分為單膜袋和復合薄膜包裝袋兩大類。其主要執(zhí)行標準有：GB/T4456-1996《包裝用聚乙烯吹塑薄膜》、GB12025-1989《高密度聚乙烯吹塑薄膜》、QB/T2461-1999《包裝用降解聚乙烯薄膜》、GB9687-1988《食品包裝用聚乙烯成型品衛(wèi)生標準》、GB9688-1988《食品包裝用聚丙烯成型品衛(wèi)生標準》等。

食品包裝袋檢驗項目

按照單膜袋和復合膜袋兩種不同的材質(zhì)，需分別進行不同的檢驗項目。

單膜袋檢驗項目主要分為三大類：一、外觀不得有對使用有礙的氣泡、穿孔、水紋、暴筋、塑化不良、魚眼僵塊等疵病；二、規(guī)格、寬度、長度、厚度偏差均應(yīng)有規(guī)定的范圍內(nèi)；三、物理機械性能包括拉伸強度、斷裂伸長率。
