Abstract: There is provided a header for packaging a roll of paper having two opposite roll ends and an outer roll surface extending between the roll ends, the outer roll surface being wrapped with a wrapping paper. The header comprises a cellulosic fiber based substrate having two surfaces and a film coated to at least a portion of one of the substrate surfaces. The film is coated to the substrate surface by extrusion of a coating comprising a mLLDPE resin. The film coated surface is heat sealable to an outside surface of an interior header affixed to one of the roll ends, thereby forming a protective cap at the roll end. The header generates less volatile compounds and/or carbon monoxide compared to a header coated with a standard LDPE, on heat sealing conditions.
