<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a polypropylene-based resin laminated foamed sheet for forming a container with a stably peelable surface film, which makes the polypropylene-based resin laminated foamed sheet stably, continuously and economically manufactured by using printing ink originally used for designedness. <P>SOLUTION: In the polypropylene-based resin laminated foamed sheet, a polypropylene-based resin film, which is printed on a polypropylene-based resin foamed sheet, is superposed in such a manner that a printing surface is directed to an inside (the side of the foamed sheet). Characteristically, the polypropylene-based laminated foamed sheet is extrusion-laminated by using a polypropylene-based resin so that the peel strength of the polypropylene-based resin film and the printing ink bonded to the polypropylene-based resin foamed sheet can be set to be in the range of 0.3-1.5 N/15 mm. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
