<p>PROBLEM TO BE SOLVED: To enable easy cutting of a synthetic resin film along a cutting line by a method where a straight line, a curved line, etc., are made with a coating containing a specific number or over of glass ceramics, fibers, etc., as reinforcing mateal on a film composed of a specific number of layers, and then another line is made coatingly in parallel to a side of the line. SOLUTION: A coating containing one or more kinds of ceramics, fibers, etc., as reinforcing materials are applied to a film containing at least one layer of a synthetic resin layer to make an edge line 2. Further, an auxiliary coating is applied parallel to its side to make an inducement line 3. A part put between the edge line 2 and the inducement line 3 is a cutting line 4. The side of the edge line 2 and a side of the inducement line 3 are coated by providing a slightly wider difference according to a curve of the edge line 2 and a branch of the cutting line 4. When the edge line 2 and the inducement line 3 are coated on the same plane or both surfaces, for example, the side is coated at an interval of 1 mm or under. When a front and a rear are independently coated, application is carried out so that the side of the front edge line 2 of the film 21 becomes parallel to the side of the rear inducement line 3.</p> |
