High gloss paper cup

摘要

A method is described for continuously producing a smooth, high gloss coating on a paper container comprising the steps of applying a substantially uniform coating of melted wax material to the outside surface of the container or sheet stock, maintaining the temperature of the wax coating above its melting point and above its congealing temperature, imparting a constant surface velocity to the outside surface of the container or sheet stock and applying a substantially uniform film of liquid coolant, particularly water, to the outside surface of the container or sheet stock whereby the surface velocity of the coolant is substantially equal to the surface velocity of the container or sheet stock.
