The unstretched polypropylene (CPP) film of Fig. 2 is made of a laminated resin film laminated with an ester adhesive,
On the flexible packaging container blank shown in (A), the shape-retaining sheet of the packaging container of the present invention of Examples 1 and 2 was prepared.
The blank of the flexible packaging container shown in FIG. 2 (A), which was pasted with heat of 30 ° C. and pressure of 0.5 kg / cm 2 , was used as the conventional example of Comparative Example 1 and Comparative Example 2. The shape-retaining sheet of the packaging container,
By sticking with heat of 350 ° C. and pressure of 1.5 kg / cm 2 , the oxygen (O 2 ) permeation amount of each is determined according to ASTM-D1434-58.
When the blank of the flexible packaging container before attachment was 5 to 7 CC / m 2 hr, the shape-retaining sheet of the packaging container of Example 1 and Example 2 was attached. The blank of the flexible packaging container that was worn was 5 to 7 CC / m 2 hr, and the flexible packaging in which the shape-retaining sheets of the packaging containers of Comparative Examples 1 and 2 were adhered 20 to 20 blank containers
It was 30 CC / m 2 hr, and in the flexible packaging container made of the laminated resin film of this practical example, deterioration of gas barrier property was not observed.

First, heat the inner blanks of the left and right heat-sealing pieces (51, 57) by using the same rectangular blank made of laminated resin film as it is, using the conventional mechanical bag making and filling equipment as it is. Put on (sticker seal), and then fold the left and right bottom bodies (63, 6
5), heat-seal the inner surface of the bottom heat-sealing piece (71) to each other (gazette seal), store the contents, and finally fold the left and right folding top bodies (43, 45). Then, the upper heat-sealed piece
Since the inner surfaces of (31) can be sealed by heat-sealing (gable top seal), mass production is possible and the manufacturing cost is low. In particular, one rectangular blank made of laminated resin film The inner surfaces of the left and right heat-sealing pieces (31,51,57,71) are completely heat-sealed, so that the top of the roof is gable roof type, which has excellent content preservation properties such as moisture resistance, waterproofness, and gas barrier properties. The obtained rectangular parallelepiped-shaped laminated resin film-made flexible packaging container is obtained.
