Abstract
Improvements in the construction of postformable laminates are disclosed by the provision of a single high basis weight, high coarseness, high kappa number sheet formed predominantly of softwood pulp, preferably southern loblolly pine, which pulp has been treated in a mechanical device that effectively imparts kinking and curling to the individual pulp fibers. The sheet is intended as a replacement for the highly extensible sheet(s) currently located on the back of the laminate farthest away from the core.
