Abstract: A valve tube assembly for a repulpable bag having a valve end portion includes, in an exemplary embodiment, a valve tube member formed from a repulpable paper material, wherein the valve tube member includes a first end, a second end, an inside surface, and an outside surface, and a water dispersible hot melt adhesive layer deposited on at least a portion of the inside surface adjacent the first end by a timed application, with a remainder of the inside surface being free of the water dispersible hot melt adhesive. The valve tube member is sized to extend into the valve end portion of the repulpable bag with the second end positioned inside the repulpable bag.

Abstract: A bag structure includes a bag body including side walls having inner and outer surfaces, and the bag body further includes a top end and a bottom end. A closure member is coupled to the top end for opening and closing the bag body, and an inner seal is formed proximate to the top end, without the use of heat driven from the outside surface of the bag wall to the inside surface of the bag wall. Further, the top end of the bag is folded over, and an adhesive member is secured to the bag body. The adhesive member includes a reinforced section and an adhesive section. The adhesive member is configured to retain the top end of the bag body in a folded over relationship until the adhesive member is severed along the reinforced section.
