PROBLEM TO BE SOLVED: To provide a combination of an ethylenic resin and a propylenic resin, both of which can be heat-sealed mutually, which are excellent in heat-sealing strength and the balance of content aptitude and heat resistance or the like, and to provide a heat-sealed article utilizing the combination. SOLUTION: The heat-sealed article is obtained by heat-sealing a film material (A), which has a heat-sealing layer comprising the ethylenic resin having specific physical properties manufactured using a metallocene catalyst, and a film material (B), which is a heat-sealing layer comprising the propylenic resin having specific physical properties manufactured using the metallocene catalyst, in the heat sealing layers of both of them. A sheet material may be a single layer material comprising a single heat-sealing layer or a laminate comprising a substrate and the heat-sealing layer. COPYRIGHT: (C)2004,JPO
