<P>PROBLEM TO BE SOLVED: To provide a resin laminated film for a cover material that essentially has a dead-folding characteristic usable for a cover material of a food vessel, shows excellent productivity and can be industrially stably supplied, and to provide a cover material made by using the resin laminated film. <P>SOLUTION: The resin laminated film for the cover material comprises at least two film-like resin layers each composed of a resin composition having a crystallization velocity different from those of others, these being laminated in the order of the crystallization velocity, the ratio of the crystallization velocity of a resin layer to that of the neighboring resin layer being 1:6 to 1:100 at a heat treatment temperature; and a heat seal layer mounted on the surface having the slower crystallization velocity of the laminated film. <P>COPYRIGHT: (C)2009,JPO&INPIT |
