Abstract
A plastic bag has a safety even when a flap is not adhered on an outer surface of a side gusset. One of the opposite end portions of the side gusset is obliquely folded in half along a fold line and interposed between the two layers of the side gusset, so that the flap is formed by the end portion between the two layers of the side gusset. The flap includes a folded edge formed by a folded inner edge of the side gusset, and an open edge formed by one of the opposite end edges of the side gusset. The flap further includes a joining edge extending straight or curved and joining the folded edge and the open edge on opposite sides of the fold line.
