Abstract: A method of forming a safer and more secure containment for the removal or isolation of harmful and/or noxious particulate materials. The containment is formed using adhesive coated plastic sheeting to form an isolated enclosure. The adhesive holds the sheeting under negative pressure and is removable with minimal damage or transfer to wall and floor surfaces.

Abstract: A linerless double-backed adhesive tape structure is disclosed. In one embodiment the tape has three tape strips each with an adhesive coated surface and an adhesive free surface. Two of the strips are joined to a center strip along its lateral edges with the adhesive coated surfaces of the two strips overlapping and adhered to the adhesive coated surface of the center strip. Also disclosed is a method of unitizing and sealing a plurality of containers. In one embodiment a double-backed adhesive tape structure is adhered to each of the containers and the containers are stacked together with the exposed adhesive side of the tape on each container adhered to the exposed adhesive side of the tape on an adjacent container. Finally, an apparatus for dispensing the double-backed adhesive tape of the present invention is disclosed.
