Abstract
Apparatuses and processes for laminating a finish layer of paper, plastics, film, foil, and other thin sheet material to corrugated material along a corrugator line. The finish layers may be single layer or composite material and are preferably, but not necessarily preprinted, reverse printed, etched or otherwise. 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.
