PURPOSE:To obtain a laminate bag for packing of food, excellent in unsealing characteristic and shock-resistant strength, by forming it with a laminate film having specified properties. CONSTITUTION:A laminate bag for packing of food is formed from the following laminate film; (a) the outermost layer is a heat-treated biaxially oriented nylon film layer made of nylon 6 and/or nylon 66 and pol(lm-xylene azipamide), (b) the intermediate layer is made of a metallic foil. (c) the inner most layer is an extended polyolefin film having a range of the orientation coefficient by the fluorescence orientation method, 0.05<=L<=0.90, 0.5<N<0.09 (L is the orientation parallel to the forming direction of film, and N is non-orientation in plane). It is preferable that MD/TD=1.2-2.5 in the nylon and polyester layer, and MD/TD>=2 in the polyolefin layer. |
