A plastic film bag, including a seam welded part, a plastic film bag body part, and a tear tape to open the plastic film bag, is disclosed. In the plastic film bag, the tear tape is made of a monodirectionally oriented polypropylene film and is attached to an outer surface of the plastic film bag at a predetermined position between the seam welded part and the plastic film bag body part. Because the plastic film bag of the present invention is realized such that the tear tape is attached to the outer surface of the plastic film bag using an adhesive, the tear tape does not compromise the function of sealing the package, but allows the package to be completely sealed, unlike a conventional tear tape attached to the inner surface of a plastic film bag.
