Abstract: A biaxially oriented film and a laminated film contain organic particles at a content of 0.001 to 20% by weight. The strength when deformed by 10% (S10) of the organic particles is in the range of 3 to 30 kgf/mm and the thermal decomposition temperature for causing 10% loss in weight thereof is not lower than 350 DEG C. The weight average diameter thereof is in the range of 0.005 to 5 mu m. The film is particularly useful as a base film of a magnetic tape.
