PURPOSE:To avoid the damage of a base material and to reduce the generation of dust by swelling plastic film on the base material by solvent and cutting this film. CONSTITUTION:When plastic thin film (for instance, cellulose nitrate film of below 10mum) formed on a smooth base material (for instance, glass plate) is cut and peeled off from the base material, the plastic thin film is initially impregnated with solvent (for example, 2-ethodiethanol) and swelled. Then, this thin plastic film is cut without generating dust nor breaking the base material by a sharp blade. |
