Abstract
A heatseal porous plugwrap made with a naturally porous combiner wrap and spray-applied hot melt adhesive. The natural porosity of the combiner wrap paper and the superficial location of sprayed adhesive greatly inhibit the penetration of adhesive to the outer surface of the paper, thus minimizing the possibility that the adhesive will interfere with the tipping process. The use of a sprayer to apply the adhesive allows for only the required amount of adhesive to be utilized and thus eliminates waste.
