ABSTRACT:
A paper roll header having a first waterproof polymeric coating over its inner face, the coating being a thermoplastic which is heat softenable at a predetermined elevated temperature for bonding to the crimped end of a wrapper around the paper roll, and a second coating on the first coating on the inner face of the roll, the second coating being in the central zone of the inner face and being non-softenable at the noted predetermined elevated temperature, so that the heat sealingly bonds to the wrapper but not to the end of the roll itself.
