(57) [Summary] [Purpose] In a packaging container or a packaging bag having an olefin-based polymer on a heat sealing surface, it has a sufficient sealing force, is easy to open at the time of opening, and has an appearance of a peeling surface. Provide an excellent easy-open container. [Structure] The following components (A), (B), and (C) An easily-openable container having a heat-sealing structure in which a surface of a polymer composition containing a component and a surface of an olefin-based polymer are heat-sealed. (A) an olefin polymer other than the following component (B): 30 (B) a linear ethylene-α-olefin copolymer which is a copolymer of ethylene and an α-olefin having 6 to 12 carbon atoms with a metallocene catalyst; 30 to 5% by weight (C) olefin A polymer having a solubility parameter in which the absolute value of the difference from the solubility parameter of the olefin polymer of the component (A) is 0.7 or more; |
