Ensulate® trays and boxes replace containers that have wax impregnation or wax curtain coat and offer improved environmental and economic benefits over traditional wax coated boxes. Multiple Ensulate® board structures are available for products that are packed or distributed in wet or cold-humid environments and trays and boxes made from our Ensulate® coating are fully recyclable. In many cases, recyclers will pay retailers to pick up Ensulate® materials along with other OCC rather than retailers paying disposal companies to landfill waxed containers.
