PROBLEM TO BE SOLVED: To provide an easy opening container having sufficient sealing strength as a packaging container or bag having a heat-sealing surface comprising a propylene resin, easily opened at the time of opening and excellent in the appearance of a peeling surface. SOLUTION: An easy opening container having a heat sealing structure is constituted by heat-sealing the propylene resin layer of a laminated film, which is composed of a layer of a resin compsn. consisting of 45-75 wt.% of a propylene resin, 5-45 wt.% of an ethylene homopolymer resin or an ethylenic copolymer resin with a density of above 0.930 g/cm3 and 5-30 wt.% of an ethylene/α-olefin copolymer with a density of 0.860-0.930 g/cm3 [wherein the wt.% of each of the components is set with respect to the sum total 100 wt.% of three components] and a layer of a propylene resin and characterized by that the thickness ratio of the resin compsn. layer to the propylene resin layer is 2 or more, to a propylene resin surface. |
