Abstract

The present disclosure provides paper wraps, paper wrapped products, such as rolled bath tissue, paper towel products, or bundles of rolled bath tissue or paper towels, and methods for covering a product or bundled products in a paper wrap. For example, printed paper wraps and their use are described, wherein the printed paper wraps comprise at least one heat-sealable adhesive that may be applied in varying locations, coverage levels, and patterns comprising different seal strengths, which may be sealed using heat and/or pressure external to the products for packaging and protective purposes.

First claim

We claim:

1. A paper wrapped product comprising:
a product covered in a paper wrap;
the product having a top surface, a bottom surface, and at least one side surface;
the paper wrap having an inside surface and an outside surface; wherein at least one portion of the outside surface of the paper wrap is coated with at least one heat-sealable adhesive;
wherein the paper wrap covers the product such that a first portion of the outside surface of the paper wrap is folded back to overlay a second portion of the outside surface of the paper wrap at a position covering the top surface of the product, a third portion of the outside surface of the paper wrap is folded back to overlay a fourth portion of the outside surface of the paper wrap at a position covering the bottom surface of the product, and a first portion of the inside surface of the paper wrap overlays a fifth portion of the outside surface of the paper wrap at a position covering the at least one side surface of the product; and
wherein at least one of the first and second portions of the outside surface of the paper wrap is coated with at least one first heat-sealable adhesive bonding the first and second portions together, at least one of the third and fourth portions of the outside surface of the paper wrap is coated with at least one second heat-sealable adhesive bonding the third and fourth portions together, and the fifth portion of the outside surface of the paper wrap is coated with at least one third heat-sealable adhesive bonding the fifth portion of the outside surface of the paper wrap to the first portion of the inside surface of the paper wrap; and
wherein the portions of the outside surface of the paper wrap coated with the at least one first heat-sealable adhesive, at least one second heat-sealable adhesive, and at least one third heat-sealable adhesive make up a total coated area of the outside surface of the paper wrap, and wherein less than about 35% of the total coated area of the outside surface of the paper wrap remains exposed on the outside of the paper wrapped product.

2. The paper wrapped product of claim 1 , wherein the product comprises at least one paper towel roll or bath tissue roll.

3. The paper wrapped product of claim 1 , wherein the product is an individually wrapped paper towel roll or bath tissue roll.

4. The paper wrapped product of claim 1 , wherein the product is an individually wrapped coreless paper towel or bath tissue roll.

5. The paper wrapped product of claim 1 , wherein the product comprises a bundle of paper towel or bath tissue rolls.

6. The paper wrapped product of claim 1 , wherein the product comprises a bundle of coreless paper towel or bath tissue rolls.

7. The paper wrapped product of claim 1 , wherein the portions of the outside surface of the paper wrap coated with the at least one first heat-sealable adhesive, at least one second heat-sealable adhesive, and at least one third heat-sealable adhesive make up a total coated area of the outside surface of the paper wrap, and wherein less than about 5% of the total coated area of the at least one first heat-sealable adhesive, at least one second heat-sealable adhesive, and at least one third heat-sealable adhesive remains exposed on the outside of the paper wrapped product.

8. The paper wrapped product of claim 1 , wherein each of the at least one first heat-sealable adhesive, the at least one second heat-sealable adhesive, and the at least one third heat-sealable adhesive is a non-wax adhesive that comprises a heat-sealable polyvinyl alcohol polyvinyl acetate.

9. The paper wrapped product of claim 1 , wherein the at least one first heat-sealable adhesive and the at least one second heat-sealable adhesive are the same as each other and different from the at least one third heat-sealable adhesive.

10. The paper wrapped product of claim 1 , wherein the portions of the outside surface of the paper wrap coated with the at least one first heat-sealable adhesive, at least one second heat-sealable adhesive, and at least one third heat-sealable adhesive make up a total coated area of the outside surface of the paper wrap, and wherein the total coated area of the at least one first heat-sealable adhesive, the at least one second heat-sealable adhesive, and the at least one third heat-sealable adhesive covers between about 35% and about 65% of the outside surface of the paper wrap.

11. The paper wrapped product of claim 1 , wherein the at least one first heat-sealable adhesive and the at least one second heat-sealable adhesive are each coated on areas of the paper wrap in a pattern providing from about 40% coverage to about 60% coverage of the coated areas.

12. The paper wrapped product of claim 11 , wherein the at least one third heat-sealable adhesive is coated on an area of the paper wrap in a pattern providing substantially 100% coverage of the coated area.

13. The paper wrapped product of claim 1 , wherein each of the first and second portions of the outside surface of the paper wrap are coated with the at least one first heat-sealable adhesive and each of the third and fourth portions of the outside surface of the paper wrap are coated with the at least one second heat-sealable adhesive.

14. The paper wrapped product of claim 13 , wherein the first portion of the inside surface of the paper wrap is also coated with at least one heat-sealable adhesive.

15. The paper wrapped product of claim 14 , wherein the outside surface of the paper wrap is further printed with ink in the form of decorative elements, patterns, informational markings, eye marks, or combinations thereof.

16. The paper wrapped product of claim 3 , wherein the bond between the first and second portions of the outside surface of the paper wrap and the bond between the third and fourth portions of the outside surface of the paper wrap each have a max load seal strength of between about 75 g f /inch width to about 150 g f /inch width, and the bond between the fifth portion of the outside surface of the paper wrap and the first portion of the inside surface of the paper wrap has a max load seal strength of between about 8 g f /inch width and about 50 g f /inch width.

17. The paper wrapped product of claim 3 , wherein the bond between the first and second portions of the outside surface of the paper wrap, the bond between the third and fourth portions of the outside surface of the paper wrap, and the bond between the fifth portion of the outside surface of the paper wrap and the first portion of the inside surface of the paper wrap each have a max load seal strength of between about 75 g f /inch width and about 150 g f /inch width.

18. The paper wrapped product of claim 3 , wherein the paper wrap has a basis weight, and wherein the basis weight is between about 12 lbs/3000 ft 2 to about 20 lbs/3000 ft 2 .

19. The paper wrapped product of claim 3 , wherein each of the at least one first heat-sealable adhesive, the at least one second heat-sealable adhesive, and the at least one third heat-sealable adhesive is applied at a dry coating weight of from about 0.2 lbs/3000 ft 2 to about 1 lb/3000 ft 2 .

20. The paper wrapped product of claim 3 , wherein each of the at least one first heat-sealable adhesive, the at least one second heat-sealable adhesive, and the at least one third heat-sealable adhesive is applied at a dry coating weight of from about 0.25 lbs/3000 ft 2 to about 0.5 lbs/3000 ft 2 .

21. The paper wrapped product of claim 5 , wherein the bond between the first and second portions of the
