<p><P>PROBLEM TO BE SOLVED: To provide relatively inexpensively a composite paperboard for drawing with which a deep drawing can be processed, a paper-made tray-like container manufactured by using this composite paperboard, and a method for manufacturing the paper-made tray-like container. <P>SOLUTION: After a number of uneven patterns (13 and 14) are made on the composite paperboard (10) prepared by forming a thermoplastic resin layer (12) on at least one face of a paperboard (11), the uneven patterns are crushed again to form a composite paperboard (15) for molding. The paper-made tray- like container prepared by using this composite paperboard (10) enables a relatively deep drawing. <P>COPYRIGHT: (C)2004,JPO</p> |
