<p><P>PROBLEM TO BE SOLVED: To provide an easily openable retort package having retort adaptability and excellent straight openability, and easily and manually openable. <P>SOLUTION: In the easily openable retort package, a film-like laminated body in which at least a surface layer, a laser beam reflecting ink layer, an intermediate supporting layer, a barrier layer, and a heat sealing layer are layered in this order are superposed with the surface layer side forming an outer side and the heat sealing layer side forming a content side, peripheral ends are heat-sealed, and an openable protion to be manually torn and opened is formed thereon. The film-like laminated body at the openable protion is half-cut from the surface layer side to a part in front of the laser beam reflecting ink layer in its sectional direction by the application of the laser beam from the surface layer side, and the straight openability is imparted in the openable part. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
