5. 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.
6. A wrapped paper roll as claimed in claim 1 , wherein the exposed adhesive comprises at least one exposed adhesive strip.
7. A wrapped paper roll as claimed in claim 6 , wherein the wrapper comprises an adhesive material layer, having a width W 2 , superposed to a first paper layer, having a width W 1 , and a second paper layer, having a width W 3 , superposed to the adhesive material layer, the widths W 1 and W 2 being wider than the width W 3 , thereby exposing the exposed adhesive layer in the second section of the wrapper.
8. A wrapped paper roll as claimed in claim 7 , wherein the width W 1 is at least equal to the width W 2 .
9. A wrapped paper roll as claimed in claim 1 , wherein the first section of the wrapper comprises a moisture barrier property layer.
10. 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.
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.
12. 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.
13. 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.
14. 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.
15. 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.
16. A wrapped paper roll as claimed in claim 11 , wherein the wrapper comprises a heat activated adhesive material layer, having a width W 2 , superposed to a first paper layer, having a width W 1 , and a second paper layer, having a width W 3 , superposed to the heat activated adhesive material layer, the widths W 1 and W 2 being wider than the width W 3 , thereby exposing the exposed heat activated adhesive strip in the second section of the wrapper and defining the exposed heat activated adhesive strip.
17. A wrapped paper roll as claimed in claim 16 , wherein the width W 1 is at least equal to the width W 2 .
18. A wrapped paper roll as claimed in claim 11 , wherein the first section of the wrapper comprises a moisture barrier property layer.
19. 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.
20. 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.
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
