SELF-CORRUGATING LAMINATES AND CORRUGATED STRUCTURES FORMED THEREFROM
摘要
<p>Self-corrugating laminates are disclosed that include first and second non-shrinkable core layers bonded together in a grid of spaced bond points arranged substantially linearly along perpendicular horizontal and vertical bond point lines; and upper and lower shrinkable film layers, each having a primary axis of shrinkage and each bonded to one of the non-shrinkable core layers along bond lines that are substantially perpendicular to the primary axis of shrinkage of the immediately adjacent shrinkable film layer. Upon shrinkage of the upper and lower shrinkable film layers a corrugated structure is formed that includes first and second core layers each having spaced structural corrugations formed therein.</p>
