PROBLEM TO BE SOLVED: To easily, rapidly and theoretically evaluate the blocking phenomenon occurring when a long material which is formed by coating ink or the like on a film and on which surface treating is carried out, is preserved as a roll. SOLUTION: In the method for evaluating resistance to blocking between actual films, the film made of plastic, paper, metallic foil or the like on which the surface treating is carried out on at least one surface thereof is overlapped on so that the treated surface is in contact with one surface of an other film. After heating and pressurizing, the shearing load between the two overlapped films is measured. COPYRIGHT: (C)2003,JPO
