Corrugated packaging for the transport of ice-packed poultry or fish, or field packaging of produce often requires a high degree of water resistance such that stacked boxes in transport or storage do not collapse. Traditionally, corrugated boxes were either curtain or cascade coated with petroleum based waxes, a practice no longer acceptable in many situations since waxed cartons are not readily recyclable and premiums must be paid for disposal. Alternatives have become recently available which include aqueous polymer coatings on linerboards and treated medium. The performance of the alternatives have been evaluated in a previous publication which illustrated that the medium must be non-wicking for wet applications. However the cost of polymer coatings exceed that of wax by several times thus pigment containing alternatives displacing polymers were sought and considered in a following paper which suggested that kaolin coatings can be used as a base coating followed by a polymer top coat to replace a conventional doubly coated linerboard.
