No. 43596, but the former involves splitting a composite film in which a synthetic resin film having compatibility with a synthetic resin molded product is layered on a metal foil, and incorporating a net-shaped or fibrous split weave yarn. Alternatively, the latter involves splitting a composite film in which a polyvinyl alcohol stretched film is layered on one side of a metal foil to form a split weave yarn, removing the attached stretched film, and connecting the metal split weave yarn to a net. It is developed or cut into a shape.
