(b) a header comprising a first surface and a second surface, wherein at least one of the first surface and the second surface comprises the self seal adhesive.
2. A roll wrap according to claim 1 , wherein the self seal adhesive comprises an outside header comprises a paper substrate having a basis weight of about 10 lbs./3000 ft 2 to about 300 lbs./3000 ft 2 .
3. A roll wrap according to claim 1 , wherein the self seal adhesive provides bonding at a temperature of less than about 150° F.
4. A roll wrap according to claim 1 , wherein the peripheral wrapper portion comprises a multi-ply layer of paper, and the first edge region and the second edge region comprise a single-ply layer of paper.
5. A roll wrap according to claim 1 , wherein the outer wrapper comprises self seal adhesive on the interior surface first edge region and on the interior surface second edge region.
6. A roll wrap according to claim 5 , wherein the header comprises an inside header comprising self seal adhesive.
7. A roll wrap according to claim 6 , further comprising an outside header.
8. A roll wrap according to claim 7 , wherein the outside header comprises a hot melt adhesive, a thermoplastic polymer, or a liquid adhesive for adhering to the first crimp and the second crimp.
9. A roll wrap according to claim 1 , wherein the outer wrapper comprises the self seal adhesive on the exterior surface first edge region and on the exterior surface second region.
10. A roll wrap according to claim 9 , wherein header comprises an outside header comprising self seal adhesive, and is constructed to bond to the first crimp and the second crimp.
11. A wrapped paper roll comprising:
(a) a papa roll having a width of about 1 foot to about 11 feet from a first end to a second end;
(b) a roll wrap packaging the paper roll and providing protection to the paper roll from moisture and mechanical impacts, the roll wrap comprising:
(i) an outer wrapper circumscribing the periphery of the paper roll along the width of the paper roll from the first end to the second end, wherein the outer wrapper comprises a peripheral wrapper portion, a first edge region forming a first crimped edge over the first end of the paper roll, a second edge region forming a second crimped edge over the second end of the paper roll, an interior surface for contacting the paper roll, and an exterior surface, wherein at least one of the exterior surface first edge region and the exterior surface second edge region or the interior surface first edge region and the interior surface second edge region comprises a self seal adhesive, wherein the self seal adhesive is an adhesive that bonds to a self seal adhesive but not to a substrate not containing a self seal adhesive; and
(ii) a header comprising a first surface and a second surface wherein at least one of the first surface and the second surface comprises the self seal adhesive.
12. A wrapped paper roll according to claim 11 , wherein the self seal adhesive provides bonding at a temperature of less than about 150° F.
13. A wrapped paper roll according to claim 11 , wherein the outer wrapper comprises self seal adhesive on the interior surface first edge region and on the interior surface second edge region.
14. A wrapped paper roll according to claim 13 , wherein the header comprises an inside header comprising self seal adhesive adhering to the outer wrapper.
