An oil-resistant sheet material which has low resistance to gas permeation and excellent oil resistance and is suitable especially for use as a packaging material for foods containing an edible oil. The oil-resistant sheet material is obtained by forming at least one coating layer from a material comprising a hydrophobized starch and a crosslinking agent on at least one side of a base in an amount of 0.5 to 20 g / m2. By incorporating a fatty acid and / or polyvinyl alcohol into this coating layer, oil resistance is improved. A coating layer comprising a fatty acid as the main component or a coating layer comprising polyvinyl alcohol as the main component may be formed on that coating layer. Thus, a coating layer composed of at least two layers may be formed.

The present invention provides an apparatus of manufacturing a corrugated sheet with which the generation of local deformation when a core is force-fitted into an outer jacket is prevented and purifying capacity is improved in a metallic carrier which is composed by winding around the corrugated sheet and a flat sheet. In an ECU 117, when the number of revolutions of forming rolls 11a, 11b reach the preset number r1 of revolutions, the center distance of the forming rolls 11a, 11b is taken as a second reference center distance d2 which is wider than the reference center distance d1 by driving motors 160, 161 and making unit holding frames 152, 153 gradually ascend. Thus, since the developed length of the corrugated sheet 10A to be formed is gradually shortened, the wave-height is also gradually lowered. When a corrugated sheet 2 and the flat sheet 3 are wound around, the wave-height in the end part of winding-around is gradually lowered and the generation of difference in level in the end part is prevented, the generation of the local deformation is prevented when the core is forced-fit into the cylindrical outer jacket 4.
