ABSTRACT:
Sample bags are produced from webs of film material by forming longitudinal seams and longitudinally spaced transverse seams and by filling the bags with a sample product between forming the transverse seams. In order to make the bags easier to handle, the longitudinal seams are thickened so that the thickness of the seams is equal to the thickness of the center of the bag. Thickening is done by rolling or folding the seams or by adding frames or strips of additional material either between or outside the seam portions of the webs. The resulting bags are more easily stacked, handled and inserted into publications for distribution.
