<P>PROBLEM TO BE SOLVED: To provide an overlap packaging body capable of preventing the appearance of a ridge-like face-face adhesion part from being damaged, and its packaging method. <P>SOLUTION: The overlap packaging is implemented over a work to be packaged by using a packaging material 20 in which a base film 21 is formed of a shrink film, and a printed layer 22 is formed on an outer surface side of the base film 21 so as to cover the total area except one end side in the width direction in the base film 21 to constitute a ridge-like face-face adhesion part CS. When rafter-affixing the packaging material 20, a transparent inner surface on one end side in the packaging material 20 and an inner surface on the other end side with the printed layer 22 formed thereon overlap each other, and the overlapped portion is held by a pair of seal rollers SR1, SR2 and heat-pressed. The temperature of the seal roller SR2 in contact with the printed layer 22 is set to be lower than the temperature of the seal roller SR1 in contact with the base film 21 so that the other end side of the packaging material 20 having the printed layer 22 formed thereon is not heated to the temperature above the melting temperature of the printed layer 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
