1. , containing the manufacture method of the Fluororesin sheet of packing material, it is characterized in that, comprising:

  • To the rolling process be rolled containing fluoro-resin, the sheet material formation resin combination of revising Mohs'"'"' hardness to be the inorganic filling material of more than 8 and the volume ratio (fluoro-resin;

    inorganic filling material) of processing aid, fluoro-resin and inorganic filling material be 30 ~ 55;

    70 ~ 45, described fluoro-resin and described inorganic filling material add up to 100Sheet material after described rolling process rolling is placed at normal temperatures, or with the heating temperatures below the fusing point of described fluoro-resin, removes the drying process of described processing aid by this, andHeat to through the dried sheet material of described drying process the firing process making it sinter at temperature more than the fusing point of described fluoro-resin.
