Novel methods for preparing masking tapes by coating a thin layer of a polyolefinic material onto a lightweight nonwoven cloth and then applying a layer of adhesive, preferably a hot melt adhesive onto the opposed surface of the nonwoven cloth; and novel masking tapes prepared thereby. In the preferred embodiments, the polyolefinic layer consists essentially of a thin stratum of a high density polyethylene and a thin layer of low density polyethylene.
