ABSTRACT:
A multi-layer paper or paperboard construction that has good moisture vapour barrier qualities and mechanical strength and is easily repulpable. The construction permits the use of a very thin PVdC/butyl acrylate barrier layer by primer and laminant layers disposed on the inside surfaces of the paper substrates. The primer and laminant layers are a blend of a inorganic pigment dispersion and a styrene acrylate binder. The multi-layer construction has particular application as a wrapper to protect bulk rolled paper and paperboard prior to shipment from the paper mill and as a linerboard facing in corrugated boxes where liner packaging requires protection against water vapour.
