<p>A process for producing a fluororesin sheet containing a filler includes a step of rolling a sheet-forming resin composition including a fluororesin, a filler and a processing aid at a roll temperature of from 40 to 80° C. The processing aid includes at least 30% by mass of a petroleum hydrocarbon solvent having a fractionating temperature of not higher than 120° C. based on 100% by mass of the amount of the processing aid. The fluororesin sheet so produced provides high stress relaxation properties along with high hermetic sealing properties even when the content of the fluororesin is low and the content of the filler is high.</p> |
