Full Wax (W). Full wax treatment is generally used on wide mouth ì closures as a caulking agent. It is difficult for many liner ì facings to provide a satisfactory seal on wide mouth containers. ì The larger the finish, the greater the tolerance in both ì container and finish. Inherent waves and dips in large finishes ì also contribute to this condition. The full wax treatment is ì generally suggested for closures 58mm and above, primarily as a ì sealing aid. It also provides an additional moisture barrier and ì acts as a lubricant similar to the LW and LF coating treatments.
