残していた。In the case of using the conventional large-sized bag as described above, if the number of times of use is expected to be 10 or more, the above-mentioned base cloth is single-layered. When sewn into a bag, for example, the bag is a large bag with a width of 1 m and the height of the filling material is 1.2.
In the case of m, if you give a sudden shock by hanging it with a crane, forklift, etc., or stack 3 or more 5 stages, at a position 30 cm to 40 cm from the bag bottom,
Opening phenomenon was noticeable at the sewn part due to shock, and the stack collapsed due to stacking, which left problems for independence and durability.

にある。As described above, the conventional large-sized bag using the single-layer base cloth is inferior in durability, so that it has been limited to repeated use about 2 to 3 times. In addition, even with the above-mentioned single base cloth, since it is stiff and hard and heavy by itself, and it takes a lot of time to sew, it is common to use the base cloth having a double structure. In the known industrial sewing machine, since the W-width base cloth does not fit into the arm of the sewing machine, it was difficult to sew it. The present invention has been made as a result of various experiments and trials to solve such a point, and the purpose thereof is to prevent the opening of the eyes, the deformation of the shape, etc. as a large bag, and the self-sustaining property. It maintains its durability and is highly durable.
It is possible to endure repeated use zero or more times, and to sew such an excellent bag body to each other by sewing the unit body of the square tubular surface portion, thereby easily manufacturing the bag body.

に便利である。The large bag of the present invention is made of polypropylene,
A bag made of a raw material of flat yarn such as polyethylene has a quadrangular tubular shape, and the unit of the rectangular tubular surface portion forming the body portion is a double cross sheet or both side edges are folded back. In addition, the pillar reinforcement band with a suspension belt is sewn over the entire length in the vertical direction in the central part. Since the overlapping parts are overlapped so as to be in contact with each other, and the overlapped part is sewn from the outer surface, the body part of the bag body has eight convenient points, namely, the corners in the vertical direction and the central part of each of the corner isosceles parts. Since it will be reinforced at the time of use, it is extremely self-supporting when used as a large bag, and is less likely to be deformed due to stretching of the body portion even when the contents are filled, which is convenient for subsequent handling.

とはない。In particular, since the central portion of the square tubular surface portion is substantially reinforced by at least three layers or more and the body portion is less stretched, the body of a truck or the like is handled when handling the contents after filling. It is highly resistant to friction against the like and piercing by a claw of a hawk lift, and is extremely durable, and can withstand repeated use, for example, 10 times or more. In addition, the bag is filled with contents, and a crane,
Even if you give a sudden suspension shock with a forklift, etc., or if you stack 5 stages of 3 or more stages, the body part does not stretch much,
There is no opening in the sewn part, and there is no loss of shape in stacking.

る。Further, even in the case of such a large bag having a bag body excellent in self-sustainability and durability, in the sewing, the rectangular tubular surface portion constituting the body portion is sewn as a reinforced unit body. However, since they are overlapped so that the inner side surfaces of the side edge portions of each other come into contact with each other and the contacting portions are sewn from the outer side surface, they can be easily sewn and manufactured even though they are large bags. .
