Large Blue Plastic Cutting Board 20 x 15 Inch - by Thirteen Chefs (CuttingBoard, LLC) Our professional grade blue poly cutting boards are engineered for food service professionals for frequent and repetitive use. Made using a multi-process injection molded manufacturing process, our HDPP (high density polypropylene) boards have superior wear and heat tolerance verses PE (polyethylene) cutting boards. Designed by chefs, the surface is lightly textured to provide a slight grip to help prevent slipping and to assist with prep. Corners and edges are rounded so the board may be picked up off the table without requiring to the slide off the station. Each cutting board is NSF certified and bears the NSF stamp and logo. HDPP is also approved for food contact.
