and at least one of: an interior roll header interposed between the lower roll end and the crimped second section of the wrapper, the interior roll header having an outer face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper; and an exterior roll header superposed exteriorly to the crimped second section of the wrapper, the second section of the wrapper comprising the exposed adhesive on an outer face thereof, the exterior roll header having an inner face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper. ### Claim 2 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the exposed adhesive comprises at least one of a heat activated adhesive and a pressure sensitive adhesive. ### Claim 3 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the exposed adhesive comprises a heat activated adhesive wherein the adhesive has been activated by heating following crimping of the second section. ### Claim 4 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the wrapper further comprises a third section, contiguous with the first section and spaced-apart from the second section, crimped over the upper roll end and forming folds with interior fold sections. ### Claim 5 (depends on 4) A wrapped paper roll as claimed in claim 4, wherein the third section comprises exposed adhesive and, in the interior fold sections of the third section, portions of the wrapper with the exposed adhesive face each other in adhesive-to-adhesive contact preventing liquid infiltration therebetween. ### Claim 6 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the exposed adhesive comprises at least one exposed adhesive strip. ### Claim 7 (depends on 6) A wrapped paper roll as claimed in claim 6, wherein the wrapper comprises an adhesive material layer, having a width W2, superposed to a first paper layer, having a width W1, and a second paper layer, having a width W3, superposed to the adhesive material layer, the widths W1 and W2 being wider than the width W3, thereby exposing the exposed adhesive layer in the second section of the wrapper. ### Claim 8 (depends on 7) A wrapped paper roll as claimed in claim 7, wherein the width W1 is at least equal to the width W2. ### Claim 9 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the first section of the wrapper comprises a moisture barrier property layer. ### Claim 10 (depends on 1) A wrapped paper roll as claimed in claim 1, wherein the second section of the wrapper comprises exposed adhesive on both sides of the wrapper, and the exposed adhesive comprises at least one exposed heat activated adhesive strip, and the interior fold sections are sealed by heat activated portions of the at least one exposed heat activated adhesive strip facing each other and bonded together in adhesive-to-adhesive contact. ### Claim 11 A wrapped paper roll, comprising: a substantially cylindrical paper roll having a lower roll end and an upper roll end, spaced-apart from the lower roll end, and an outer roll surface extending between the lower and upper roll ends; and a wrapper having a first section covering the outer roll surface of the paper roll, and a second section covering the lower roll end, the second section having an exposed heat activated adhesive strip on at least an outer side of the wrapper, the second section being crimped over the lower roll end and forming folds with sealed interior fold sections wherein portions of the exposed heat activated adhesive strip face each other and are bonded together in adhesive-to-adhesive contact preventing liquid infiltration therebetween; an interior roll header interposed between the lower roll end and the crimped second section; and an exterior roll header superposed exteriorly to the crimped second section of the wrapper and being bonded to the exposed heat activated adhesive strip. ### Claim 12 (depends on 11) A wrapped paper roll as claimed in claim 11, wherein the interior roll header comprises a heat activated adhesive layer applied on an outer face thereof and being bonded to the crimped second section of the wrapper. ### Claim 13 (depends on 11) A wrapped paper roll as claimed in claim 11, wherein the exterior roll header comprises a heat activated adhesive layer applied on an inner face thereof and being bonded to the crimped second section of the wrapper. ### Claim 14 (depends on 11) A wrapped paper roll as claimed in claim 11, further comprising a third section of the wrapper, contiguous with the first section and spaced-apart from the second section, crimped over the upper roll end and forming folds with interior fold sections. ### Claim 15 (depends on 14) A wrapped paper roll as claimed in claim 14, wherein the third section comprises an exposed heat activated adhesive strip and, in the interior fold sections of the third section, portions of the exposed adhesive strip face each other in adhesive-to-adhesive contact preventing liquid infiltration therebetween. ### Claim 16 (depends on 11) A wrapped paper roll as claimed in claim 11, wherein the wrapper comprises a heat activated adhesive material layer, having a width W2, superposed to a first paper layer, having a width W1, and a second paper layer, having a width W3, superposed to the heat activated adhesive material layer, the widths W1 and W2 being wider than the width W3, thereby exposing the exposed heat activated adhesive strip in the second section of the wrapper and defining the exposed heat activated adhesive strip. ### Claim 17 (depends on 16) A wrapped paper roll as claimed in claim 16, wherein the width W1 is at least equal to the width W2. ### Claim 18 (depends on 11) A wrapped paper roll as claimed in claim 11, wherein the first section of the wrapper comprises a moisture barrier property layer. ### Claim 19 (depends on 11) A wrapped paper roll as claimed in claim 11, wherein the second section of the wrapper further comprises an exposed heat activated adhesive strip on an inner side of the wrapper and the interior fold sections are sealed by heat activated portions of the heat activated adhesive strips facing each other and bonded together in adhesive-to-adhesive contact. ### Claim 20 (depends on 11) The wrapped paper roll as claimed in claim 11, wherein the first section comprises an inadhesive inner face in contact with the outer roll surface. ### Claim 21 A wrapped paper roll, comprising: a paper roll having a lower roll end and an upper roll end, spaced-apart from the lower roll end, and an outer roll surface extending between the roll ends; a wrapper having a first section covering the outer roll surface of the paper roll, and a second section covering at least a portion of the lower roll end, the second section having exposed adhesive on at least one side of the wrapper, the second section being crimped over the lower roll end and forming folds with interior fold sections wherein portions of the wrapper with the exposed adhesive face each other and are bonded together in adhesive-to-adhesive contact preventing liquid infiltration therebetween; and at least one of: an interior roll header interposed between the lower roll end and the crimped second section of the wrapper, the interior roll header having an outer face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper; and an exterior roll header superposed exteriorly to the crimped second section of the wrapper, the second section of the wrapper comprising the exposed adhesive on an outer face thereof, the exterior roll header having an inner face with adhesive properties in contact with the exposed adhesive and being bonded to the crimped second section of the wrapper. ### Claim 22 (depends on 21) The wrapped paper roll as claimed in claim 21, wherein the exposed adhesive comprises a heat activated adhesive wherein the adhesive has been activated by heating following crimping of the second section.
