Abstract

A shippable bundled product including a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another so as to form a bundle. The bundle is packaged by a second package material. The second package material has a shrinkage factor relative to the bundle of less than zero.

First claim

The invention claimed is:

1. A shippable bundled product comprising:
a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another to form a bundle, each of the plurality of paper product rolls having a roll density between 9.5 cc/g to 12 cc/g,
the bundle being packaged by a second package material that is heat shrunk relative to the first package material,
wherein:
the second package material has a shrinkage factor relative to the bundle of less than zero so that the second package material protrudes into spaces between the paper product rolls,
a circumference of the second package material prior to heat shrinking is 25 mm or greater than a circumference of the bundle,
the circumference of the second package material after heat shrinking is 10 mm or smaller than the circumference of the bundle,
during the heat shrinking, more heat is applied to a top and a bottom of the bundle as compared to sides of the bundle,
the first package material comprises high density and low density polyethylene, and
the second package material comprises high density and low density polyethylene.

2. The product of claim 1 , wherein the second package material has a higher quantity of high density polyethylene as compared to the first package material.

3. The product of claim 1 , wherein the second package material comprises one or more outer layers that are comprised of 10-100% polypropylene.

4. The product of claim 1 , wherein at least one of the first and second package materials comprise laminated layers of polypropylene film.

5. The product of claim 1 , wherein the first package material has a higher percentage of anti-block resin as compared to the second package material.

6. The product of claim 1 , wherein the second package material comprises a number of layers within the range of 3 to 5.

7. The product of claim 6 , wherein a center layer of the second package material comprises a higher percentage of high density polyethylene as compared to outer layers of the second package material.

8. The product of claim 1 , wherein the first package material has a higher quantity of anti-block resin on a side in contact with the second package material as compared to a side in contact with the individually packaged paper product rolls.

9. The product of claim 1 , wherein a puncture resistance of the second package material is between 800-1200 gf.

10. The product of claim 1 , wherein the second package material has a thickness between 1.0 to 3.5 thousands of an inch.

11. The product of claim 1 , wherein the individually packaged paper product rolls are arranged relative to one another in a staggered/interlocking stacking pattern.

12. The product of claim 1 , wherein the second package material is subjected to heat treatment.

13. The product of claim 12 , wherein the second package material has a lower crystallinity after the heat treatment.

14. The product of claim 12 , wherein the second package material has a surface area that is lower after the heat treatment.

15. The product of claim 12 , wherein a temperature range of the heat treatment is between 300-400 degrees Fahrenheit.

16. The product of claim 12 , wherein a duration of the heat treatment is between 20 to 45 seconds.

17. The product of claim 12 , wherein the second package material exhibits anisotropic properties after heat treatment.

18. A shippable bundled product comprising:
a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another to form a bundle, paper product that makes up the plurality of paper product rolls having a bulk greater than 400 microns, each of the plurality of paper product rolls having a diameter less than 122 mm, a roll width equal to or greater than 4 inches, and a roll density between 9.5 cc/g to 12 cc/g,
the bundle being packaged by a second package material that is heat shrunk relative to the first package material, wherein:
a circumference of the second package material prior to heat shrinking is 25 mm or greater than a circumference of the bundle,
the circumference of the second package material after heat shrinking is 10 mm or smaller than the circumference of the bundle,
during the heat shrinking, more heat is applied to a top and a bottom of the bundle as compared to sides of the bundle,
the second package material has a shrinkage factor relative to the bundle of less than zero so that the second package material protrudes into spaces between the paper product rolls, and
the first package material comprises high density and low density polyethylene and the second package material comprises high density and low density polyethylene.

19. The product of claim 18 , wherein each of the plurality of paper product rolls has a Kershaw Firmness of less than 4 mm.

20. A shippable bundled product comprising:
a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another to form a bundle, each of the plurality of paper product rolls having a roll density between 9.5 cc/g to 12 cc/g,
the bundle being packaged by a second package material that is heat shrunk relative to the first package material, the second package material having a melting point between 120 and 140 deg C,
wherein:
a circumference of the second package material prior to heat shrinking is 25 mm or greater than a circumference of the bundle,
the circumference of the second package material after heat shrinking is 10 mm or smaller than the circumference of the bundle,
during the heat shrinking, more heat is applied to a top and a bottom of the bundle as compared to sides of the bundle,
the second package material has a shrinkage factor relative to the bundle of less than zero so that the second package material protrudes into spaces between the paper product rolls, and
the first package material comprises high density and low density polyethylene and the second package material comprises high density and low density polyethylene.
