ABSTRACT:
The invention provides a method of making thermoplastic resin-coated paper which comprises coating a paper sheet with a liquid thermoplastic resin, passing the thermoplastic resin-coated paper sheet through a nip of a pressure roll and a thermally conductive medium to form a resin-medium interface, heating the interface to a temperature of from 35.degree. C. to 350.degree. C. for a nip time period of from 0.002 to 10 seconds and a pressure of from 17,500 to 1,750,000 Pa-m, cooling the interface to a temperature of -73.degree. to 32.degree. C. for a cooling time period of from 0.001 to 100 seconds, and separating the thermoplastic resin-coated paper from the medium.
