Pressure-sensitive adhesive tapes

摘要

A vapor permeable article includes a porous backing substrate and an open fabric applied to one surface of the backing substrate. The open fabric has a greater porosity than that of the backing substrate. The open fabric is coated with an adhesive in such a manner that the open fabric remains porous and vapor permeable. The coated article can have a greater tensile strength in the cross direction than in the machine direction, and the adhesive can penetrate into at least a portion of a thickness of the porous backing.
