Notes

“Two methods for coating boxes or other paper products with liquid additives, such as wax, are conventionally used. The first is identified as a curtain coating process. This design incorporates a medium that is impregnated with hot wax and then becomes a corrugated box. A completed, i.e., combined, board is passed through a curtain of hot wax, in a procedure commonly known in the art of paper making as "curtain coating." First one side and then the opposite side are coated with hot wax. However, due to the conditions necessary to perform the curtain coating process, fire becomes a significant risk.

Another conventional paper coating process is "cascading" The cascading wax procedure is different from the curtain coating procedure in that a regularly corrugated box of any shape or size can be stood on end, such that the corrugated flutes are vertical, to allow the hot wax to permeate the entire structure, with a wax cascading around and through the container in a flat position that is easy to stack for shipping. In contrast to the curtain coating process, the cascading process requires the box to be fully formed prior to application of the wax or other liquid additive. This is considered the better performing wax box of the two described.”
