Ahlstrom-Munksjö LabSorb coated paper is a double-layered surface protection that protects benches and working areas from spilled chemicals, corrosive materials, as well as toxic, infectious or radioactive substances. Spills are quickly absorbed into the surface layer of cellulose material (top layer) and prevented from penetrating to the surface of the work bench by a thin coating of polyethylene that serves as a carrier for the absorbent layer (bottom layer).
