<p><P>PROBLEM TO BE SOLVED: To provide a blank for a paper container for manufacturing the paper container capable of easily forming a peel starting part and simply and reliably peeling a resin film. <P>SOLUTION: A rolled web is formed of a laminate in which a resin film is affixed to the whole surface of a cardboard in a peelable manner, and a blank 10 for a paper container is manufactured by punching the rolled web. A peel starting part P1 is formed by a cut line p formed in the cardboard so that the direction for starting the peel of the resin film is substantially orthogonal to the direction of a grain of the cardboard (the direction of an arrow). The paper layer is not completely cut off at the cut line p, and even when the paper is peeled in an affixed manner to the resin film as the resin film is peeled, the peel from the peel starting part P1 is performed against the paper grain, the paper is peeled immediately, and the resin film is peeled from the cardboard at a boundary surface. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
