This STIL 35mm x 1,000 ft. Reel Capacity Film Can is the first choice of museums, corporate archives, studios and labs. Made from inert polypropylene, the can features a unique venting chimney that lets damaging heat and gasses escape. Film sits on a platform that ensures uniform ventilation over and under the film and protects the edges of the film against indentations. Stoppers prevent the film from coming in contact with the lid for added protection.
