<p>PROBLEM TO BE SOLVED: To manufacture a laminated polyamide resin sheet of high quality suitable for packaging food with good productivity. SOLUTION: The laminated polyamide resin sheet discharged from a cap in a molten state is charged by the application of voltage to the electrode arranged above the sheet and brought into close contact with a rotary cooling body to be cooled. As a resin laminated to a polyamide resin, a thermoplastic resin A, of which the melt specific resistance is 10 times or more that of the polyamide resin, is used.</p> |
