Our PolyTack Entrance Mat is made from an incinerable polyethylene film that removes foot borne particulate before entering the clean room area. Seamless, one-piece construction allows full surface coverage and eliminates gaps between mats for large surfaces. Numbered tabs provide easy identification and sheet separation. Only .065" thick, our mat allows easy mobility for carts and wheeled machinery for removal of wheel borne contaminants. The material contains a special anti-microbial agent to provide long-lasting protection against bacterial growth. All cases have four mats per case, 30 sheets per mat, except PTM-103P. PTM-103P has six mats per case, 15 sheets per mat.
