More Information
Summary:Provided is a polystyrene-based film ensuring low costs for ginning. To this end, the polystyrene-based film comprises a syndiotactic polystyrene-based resin and a spherical filler, and is biaxially oriented, while having gloss of 30% or less, surface roughness (Ra) of 0.8 [mu]m or more, and tensile elongation of 15% or more. Preferably, the spherical filler is amorphous silica, more preferably the spherical filler is fused silica.
