PROBLEM TO BE SOLVED: To provide a package that is excellent in seal stability compared to a cohesion breakage type sealant in terms of the face-to-face seal of a film package, ensures both easy-to-open performance and sealing performance, and is easy to take its content out of it. SOLUTION: The package 100 is formed from a laminated film 110. The seal layer of the laminated film 110 comprises a co-extrusion layer peelable between layers, the co-extrusion layer including a support layer formed from polypropylene as its main component, and a peelable layer formed from a resin composition of polypropylene and polyethylene as its main component. An opening area 150 is defined in the surface of the package 100 by providing a cut line 111 in the surface of the package 100. The laminated film 110 is torn from the opening area 150 along virtual line 160. The laminated film 110 is cut off as it is in such a manner as to be peeled at a lateral seal 132 interlaminarly. Consequently, a large opening 110a' is defined in it. COPYRIGHT: (C)2006,JPO&NCIPI
