<P>PROBLEM TO BE SOLVED: To provide a partitioned packaging bag capable of separately storing two or more kinds of materials and mixing them when in use without unsealing the packaging bag, free from a fear of both materials mixing during transportation and storage, and capable of easily mixing them when in use. <P>SOLUTION: The partitioned packaging bag consists of thermoplastic resin films 2a and 2b forming a bag body 3 and a partition film 4 for partitioning the bag body. The partition film 4 is formed by overlapping two ribbon-like materials having a heat-sealable layer and a weak heat-sealable layer with the weak heat-sealable layers inside and thermally fusion-bonding one of side rims. The partition film 4 is provided across two sides of the bag body 3, and the heat-sealable layer on the side of a free side rim is thermally fusion-bonded to the internal surface of the thermoplastic resin films 2a and 2b of the bag body 3 along the free side rim, thereby forming the partitioned packaging bag 1 having the bag body 3 with its inside partitioned. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
