摘　　要：用有机溶剂浸泡药物和奶粉两种复合膜包装袋,让其每一层分开。经FT-TR仪及X射线萤光光谱仪检测,结果表明:药物包装袋内层膜的材质是聚乙烯(PE),外层膜的材质是聚丙烯(PP)。奶粉包装袋内层膜的材质是PE;中间层是金属铝膜;外层膜的材质是聚对苯二甲酸乙二醇酯(PET)。Two kinds of the complex film packets for medicine and milk powder are immersed in the organic solvent, then the layers are separated and identified by using FT-IR and X-ray fluorescence spectrum. The results obtained immediate that for the medic packet the inner film is made of polyethylene (PE) and the outer film is made of polypropylene (PP) . For the milk powder packet the inner film is made of PE, the middle film is made of aluminium, the outer is made of polyethylene glycol-p-terephthal ate (PET) .
