Abstract
Preparation of laminated corrugated material at the dry end of a corrugating line, and products so formed. Processes of the present invention laminate one or more finish layers of paper, thermoplastic, metal, foil, cloth, film or other thin material of any required width to suit a customer's needs, preferably between the rotary shear and the slitter/scorer station. The finish layers may be single layer or composite material and are preferably, but not necessarily preprinted, reverse printed, etched or otherwise the recipient of graphic images prior to the corrugation operation. The finish layers may be produced, supplied and run in any desired width to suit a customer's needs, without the need to engage in the planning, expense and scheduling necessary to run an entire full width roll of preprint material as single face or double face liner on the corrugator, and without the problems inherent in applying graphics to containers or cartons during the conversion process.
