(Food Drug & Plastics - Suppliers' Forum) New 53-485SR Flapper closure is a one-hand, one-step dispensing closure that provides ease of opening enhancements and greater sift resistance. Self-cleaning design prevents clogging, and deep thumbtab undercut facilitates opening. Sift-resistant design allows the closure to be used without a liner. The 53-485SR comes in a twin-flap option with one side opening to 0.3-inch holes and the other to a wide pouring aperture. Potential applications include spices and seasonings, grated cheese, dry food products and pet food/care products.
