Professional HDPE Plastic Cutting Boards by Thirteen ChefsUsed by food service professionals, our plastic cutting boards are designed for the rough environment of restaurant kitchens. Made from industrial grade HDPE plastic, our boards help keep kitchens clean and sanitary, as our engineered plastic is resistant to warping, knife scarring, stains. HDPE is a naturally heavier material (but not too heavy), helping it stay in place while using. The surface of the board also features micro texturing to assist with grip and cutting. Cleaning is trouble-free as each board is designed to fit into any and all standard home or commercial dishwashers. Our plastic poly material can withstand temperatures up to 185 degrees Fahrenheit (compare that with 145 degrees for standard polyethylene), ensuring that the cutting board is safely disinfected without ruining or warping the board.Our basics 3 pack set includes white, green and red for daily home use for separate tasks.About Thirteen Chefs - We are a Seattle based team of industry pros that designs and manufactures professional kitchen wares and tools.
