Abstract
The present invention is directed to developer solution trapping chips for use in a peel-apart type instant film unit, wherein the developer solution trapping chips are manufactured by cutting a continuous chip blank obtained by contour extrusion, which sets quickly, exhibits little deformation when wound on a reel, and produces a limited amount of swarf in cutting operation. The developer solution trapping chips are made of glycol-modified polyester and have preferably a trapezoidal or semicircular cross section.
