An exemplary moisture barrier membrane comprises a waterproof adhesive layer, a carrier support, and a release liner composite having a paper sheet, cutting strings, a polyolefin coating or film for holding the strings against the paper and apart from the waterproof adhesive layer, and a release agent such as silicone or wax over the polyolefin coating or film. This construction allows for relatively thin paper and strings to be used, such that tear resistance is conferred upon the release liner composite as a whole.
