摘要： A wound paperboard tube having enhanced burst strength in high-moisture conditions up to and including complete and prolonged submersion in liquid water comprises a plurality of paperboard plies formed from a pulp comprising papermaking furnish and an effective amount of a size such that the paperboard plies have reduced moisture add-on when submerged in water, relative to paperboard plies formed from a pulp comprising the identical furnish but without the size. The plies are wound one upon another about an axis of the tube and adhered together with a water-resistant adhesive comprising a polyvinyl composition containing a cross-linking agent for inducing cross-linking of the adhesive.
