Silicone rubber roll for embossing molding, method and apparatus for producing plastic film by using same, and surface protective film

Provided is a silicone rubber roller for embossing molding, which has no minute defects on the surface and does not cause protrusions on the surface of a plastic film obtained by embossing molding. In the silicone rubber roller for embossing molding, the silicone rubber layer on the surface contains spherical solid particles, and in the spherical solid particles, the volume contents of spherical solid particles having a particle diameter of 0.8 [mu] m or less and spherical solid particles having a particle diameter of 30 [mu] m or more are respectively 1% or less of the volume of the entire spherical solid particles. 本发明提供在表面没有微小的凹陷缺陷、进而在压花成型而得的塑料膜表面不产生突起的压花成型用有机硅橡胶辊。就本发明的压花成型用有机硅橡胶辊而言，表面的有机硅橡胶层包含球状固体粒子，在球状固体粒子中，粒径为0.8μm以下的球状固体粒子及粒径为30μm以上的球状固体粒子的体积含有率分别为球状固体粒子整体的体积的1％以下。
