A method of making a laminate for use in making a label or the like from a paper fibrous material layer, including the steps of applying a liquid release coating to one surface of the paper layer and drying it thereon, stabilizing the release coated paper layer at about 50 percent relative humidity, thereafter forming a plurality of weakened reduced thickness continuous score lines in the other surface of the paper layer by mechanically crushing or compacting the fibers in the paper at the scored line to less than 50 percent of the original thickness of the paper, and laminating a layer of adhesive and a face sheet to said paper layer with said adhesive layer being intermediate the paper layer and said sheet and being bonded to said one surface of said paper layer. 2. A method of making a laminate for use in making a label or the like, comprising applying a liquid release coating to one surface of a paper fibrous material layer and drying it thereon, exposing the dried coated paper layer to humid air and stabilizing it at about 50 percent relative humidity, forming a plurality of weakened reduced thickness continuous score lines in the other surface of the paper layer by mechanically crushing or compacting the fibers at the scored line to about 25 50 percent of the original thickness of the paper, and laminating a layer of adhesive and a face sheet to said paper layer with said adhesive layer being intermediate the paper layer and said sheet and bonded to the one surface of said paper layer.
