PROBLEM TO BE SOLVED: To solve a problem that a particular technology to specifically determine a best place for non-slip processing in a garbage bag having a unique wave shape opening is not developed even if inking, coating and printing with a non-slip function on the inner surface and outer surface of the opening of the garbage bag are performed for eliminating a defect that the sheet of the opening is unsuccessfully open since front and rear inner sheet surfaces at the opening are tightly adhered and the belly of a finger and the front surface of the opening of the garbage bag are slipped when a user intends to open flaps at the front and rear surfaces of the center of the opening by sliding the finger in a conventional garbage bag. ! SOLUTION: A garbage bag made of a synthetic resin film material formed with chevron-shaped projection front and rear surface flaps at a center by making an opening edge part to be a wave shape and substantially rectangular right and left grip parts sandwiching a trough pa |
