(Effects) The present invention inserts the rod insertion holes and long rod insertion holes provided on the left and right sides of the folded plastic bags according to the invention into the left and right bag holding rods of the stand for opening plastic bags. , held in the bag holding rod and pulled out one by one from the front row of plastic bags, but when the front wall of the front row of plastic bags is pulled forward by holding the tongue part of the front wall. The plastic bag is bent forward, the right and left front overlapping parts are expanded, and the left and right rod insertion slots of the plastic bag move along the bag opening rod portions of the left and right bag holding rods while opening the bag. In this case, the left and right rod insertion slots are long holes that extend outward from the bag opening rod, so even if the front wall is curved, they can be easily moved relative to the bag opening rod without resistance. I can do it.

In addition, with the left and right front overlapping parts expanded in this manner, the left and right rear overlapping parts are pulled out as if unfolding forward, but the left and right rod insertion holes drilled in the left and right overlapping parts are inserted into the left and right bags. When moving along the holding rod, there is some resistance between it and the holding rod, which prevents the back wall from moving forward as the front wall moves, ensuring that the plastic bag can be opened securely. It has excellent practical effects such as being carried out in a stable state.
