Packaging header for a roll of material and method for packaging a roll of material

Abstract

A packaging for a roll of material, such as a roll of paper, having a cylindrical wall and opposing ends. The packaging comprises a wrapper to be wound about the cylindrical wall of the roll, the wrapper being sized to extend beyond the opposing ends of the roll for folding and crimping extending edges of the wrapper onto said opposing ends; and at least one header to be fitted against the respective ends of the roll and comprising an embossed cellulosic substrate to absorb a volume of crimps when the wrapper is folded and crimped onto the ends and pressure is applied against the ends of the roll. It also relates to a method and a packaging kit for packaging a roll of material, a packaged roll of material, and a packaging header.
