Abstract
A method of processing pulp laps and a soluble strap material for holding such laps in a bale are disclosed. In accordance with the method the laps are maintained in the configuration of the bale by soluble straps comprised of PVA and are immersed in a pulping bath while still confined by the straps. The straps rupture and dissolve in the pulping bath releasing the paper laps. The straps are formed to maximize exposure of the PVA increments to the pulping bath to accelerate dissolving and may incorporate fillers of pulpable material to maintain the PVA increments in a separated condition.
