Claims

[Scope of Claim for Utility Model Registration] 1. In a synthetic resin bag body a manufactured by side-sealing and bag opening processing a soft synthetic resin sheet or tube bag material, the bag bottom part is placed on both sides with the inner fold part 1 in between. The outer folded parts 2, 2' are folded into a bellows folded bottom 3 in which the outer folded parts 2, 2' are lined up, and both sides of the folded bottom 3 are side heat sealed 4, 4' with bag processing, and the outer folded parts 2, 2' are
Heat seal 5 in parallel along the lower folded edge,
A round bottom bag made of synthetic resin, characterized by being made with a 5'. 2. Make the outer folding parts 2 and 2' longer than the inner folding part 1 by making the bellowing fold of the bottom 3.
Bag-processed side heat seals 4, 4' are applied to the lower ends of the outer folded parts 2, 2', and heat seals 5, 5' are applied parallel to the outer folded parts 2, 2', and the inner folded parts 1 are 2. The synthetic resin round bottom bag according to claim 1, wherein the outer folded portions 2, 2' are formed in line with the lower folded edge of the inner folded portion 1 so that the long range of the outer folded portions 2, 2' to be crossed corresponds to the skirt edges 6, 6'. .
