PROBLEM TO BE SOLVED: To make each room enough divided during distribution and to make a temporarily sticked part released when a retort pouch is used and to mix different kinds of contents as the result by using an undrawn polypropylene resin as an inner heat-sealable film and changing heat seal conditions for the peripheral part of a bag and the temporarily sticked part for dividing the bag into two rooms. SOLUTION: Two sheets of laminated bodies A wherein at least a heat- resistant base film 1 and a heat-sealable film 2 are successively laminated from the outside and as the heat-sealable film 2, the surface of an undrawn polypropylene resin film 2' consisting of a compsn. wherein an ethylene- propylene copolymer is a main component and an olefin rubber component is added is laminated. Then, a bag body is constituted by forming a heat seal part 4 on the peripheral part and a temporarily sticked part 5 is provided at a specified position and different kinds of contents 6 and 7 are stored in two divided rooms. In this case, the temporarily sticked part 5 is heat-sealed under a condition being milder than the heat seal temp., pressure and time of the seal part 4 of the peripheral part. |
