Abstract: A balanced dimensionally stable laminate uses a web carrier which is removably attached to a layer of the laminate during lamination and processing. The web carrier maintains dimensional stability of the layers of the laminate during lamination and processing and after removal of the web carrier. The web carrier is removed if at all only after the laminate is formed and processed. The bonding force of the web carrier with at least one of the polymers layer resists forces which would otherwise dimensionally distort the layers of the laminate or design features thereof during lamination, particularly in thermal roll-forming lamination. The layers of the laminate, which may include print and texture design features, remain dimensionally stable after removal of the web carrier. The web carrier can be removed at any time prior to or after final application of the laminate to a substrate.

Abstract: A card embossing system for embossing information onto a sheet of material prior to cutting individual cards from the sheet is disclosed. Information is embossed onto the sheet in a pattern of rows and columns. Information on adjacent columns is offset relative to one another.

Abstract: A tear-resistant flexible hinge structure is placed between a pair of substantially rigid panels so as to permit the panels to be hinged one with respect to the other, where the flexible hinge is formed from a plastics material such as polyvinyl chloride. The hinge structure is formed under heat and pressure so as to comprise at least three parallel rows of alternating flat and raised portions, in staggered relationship. This causes a structure whereby any rip or tear which starts in the formed flexible hinge cannot continue because it will encounter a discontinuity in the configuration and thickness of the material, which precludes further propagation of the rip or tear. Typically, after the hinge structure has been formed, it is configured in a semi-circular cross section, re-heated and cooled, so as to set and have a memory in its closed configuration as opposed to the originally pre-formed flat, open configuration.
