PURPOSE:To eliminate the dispersion in the quality of each material due to differences of physical conditions encountered in printing process by a method in which a set of two plastic materials are concurrently printed by a single printer. CONSTITUTION:Printing is made concurrently on the surface and back sides of a multi-layered laminate sheet 1 having peelable interfaces 5 and 6 by a single printer to obtain a pattern in which patterns m1 are matched with patterns m2. The first synthetic resin layer 3 and the second synthetic resin layer 4 as molding materials for the surface and back sheets of a bag or as the body and cover of a container are separated from the core layer 2 to form one molding. |
