Abstract
A paper bag formed from a unitary blank and having a longitudinal seam running along its length. The seam is of a double layer of paper and has two spaced and parallel adhesive areas joining the two layers. A pair of parallel perforated lines border respective adhesive areas. The perforated lines define a tear strip on the outermost one of the double layers. The tear strip is provided on its usually hidden surface with indicia, so that after tearing it away, the user will be notified by the indicia of the winning of a prize offered by the vendor of product placed within the bag.
