<p>A device for impregnating a paper web with a molten polymer to produce a paper with improved resistance to oil and grease are provided. The device includes, as part of an on-machine process, an ordinary paper web (10) composed of cellulose or synthetic fibers, a polymer applicator (16), a hot reel (23), and a winding reel (26). The web, which is created through a series polymer onto the surface of the web. The web is next transferred to a hot reel, which maintains the temperature of the molten polymer above its melting point and thereby facilitates wicking of the molten polymer into the web. After the web passes the hot reel, it is wound onto a winding reel, where additional wicking occurs until the molten polymer cools to a temperature below its melting point. The invention further includes a method for impregnating a web of fibers and a polymer impregnated paper with improved resistance to oil and grease, produced by the described method.</p> |
