Object of the present invention is put up aims to cut off or a rocking back and forth standing pouch (Standing Pouch) appearance avoid distortion.; Standing pouch is between the release erected by filling the contents, as the structure is a concentrated load on either side at the bottom and around, this is necessarily the ground and cracks at the bottom center portion of the film occurs after, and the film material flexible, so over time by the weight of the filling while lifting the side reduced the gap distorted the characteristics that top wry.; Until now, in order to improve these evils abroad, but are commercialized are designed in the form crush the both ends of the pouch with curved, the present design is time-lapse if the deceased a myriad of small wedge in the pouch at the bottom by the height of the cracks in the gaps are removed between the compensation by the size of the cracks by applying the principle that is possible to prevent deformation by cutting with a gentle curve to the pouch at the bottom there is no back and forth from the initial shaking of which the weight of the contents in contact with the ground pouch according so evenly distributed at the bottom over time does not occur any distortion.; Furthermore, the present invented is therefore also possible to change the height or shape of the pouch maintaining the structural stability by a gentle curve at the bottom of the cut is convenient to use the pouch to the container itself, has an effect that can be improved in a variety of differentiated shape.
