Abstract: A seal bar construction is disclosed for thermally joining layers of polymeric web material. The construction comprises an elongate seal bar having an extremely hard sealing surface with a Vickers hardness greater than 1800. This hard surface may be polished to have a roughness Ra of less than 1 micron. The resulting sealing surface has improved non-stick properties and can be applied directly to the polymeric web.
