Abstract
A widthwise-stretched film is lap-sealed on one side of a backing paper, and polyethylene is extruded and coated on the surface of said film to form a release layer thereon. A pressure-sensitive adhesive composed mainly of polyacrylic ester is then coated on the other side of the backing paper. In this manner, a paper-backed adhesive tape of the pressure-sensitive type is prepared.
