Abstract

Segmented wrapping materials and related methods. In some embodiments, a plurality of individual segments of a film or other wrapping material may be placed on a single roll or core and each opposing edge of each segment of such roll/core may be folded or otherwise reinforced to improve the strength of the film and thereby improve containment of a pallet or other items being wrapped with the material.

First claim

The invention claimed is:

1. A roll of wrapping material, comprising:
an elongated core;
a plurality of roll segments, wherein each of the plurality of roll segments comprises a hollow center, wherein the elongated core extends through each of the plurality of roll segments, wherein each of the plurality of roll segments is separated from each adjacent roll segment of the plurality of roll segments by a fixed gap, and wherein each of the plurality of roll segments comprises a first reinforced edge at a first end of the roll segment and a second reinforced edge at a second end of the roll segment opposite the first end such that there are at least four reinforced edges positioned on the elongated core simultaneously for wrapping one or more objects simultaneously using the plurality of separated roll segments, wherein the roll is configured to maintain the fixed gap between each adjacent roll segments of the plurality of roll segments; and
at least one spacer positioned between each adjacent roll segments of the plurality of roll segments, wherein the at least one spacer is configured to prevent adjacent roll segments from interfering with each other.

2. The roll of wrapping material of claim 1 , wherein the first reinforced edge and the second reinforced edge each comprises a hemmed edge.

3. The roll of wrapping material of claim 1 , wherein the first reinforced edge and the second reinforced edge each comprises a length of between about 0.25 and about 1.5 inches.

4. The roll of wrapping material of claim 1 , wherein the plurality of roll segments comprises a first outer roll segment, a second outer roll segment opposite the first outer roll segment, and an inner roll segment positioned in between the first outer roll segment and the second outer roll segment.

5. The roll of wrapping material of claim 4 , wherein each of the plurality of roll segments is positioned on the elongated core with spacing between each adjacent roll segment of between about ¼ and about ¾ of an inch.

6. The roll of wrapping material of claim 1 , wherein each fixed gap comprises a distance between about 0.125 inches and about 1 inch.

7. The roll of wrapping material of claim 1 , wherein the wrapping material comprises a thermoplastic stretchable packaging film.

8. The roll of wrapping material of claim 1 , further comprising a wrapping machine, wherein the roll of wrapping material is coupled with the wrapping machine to allow the wrapping machine to wrap one or more objects with the wrapping material.

9. The roll of wrapping material of claim 8 , wherein the one or more objects comprises a pallet having a plurality of objects stacked thereon.

10. The roll of wrapping material of claim 8 , wherein the wrapping machine is configured to wrap the one or more objects by forming overlapping regions in which material from one of the plurality of roll segments at least partially overlaps material from another of the plurality of roll segments.

11. The roll of wrapping material of claim 10 , wherein the wrapping machine is configured to move the roll of wrapping material up and down along a portion of the wrapping machine to form the overlapping regions.

12. The roll of wrapping material of claim 10 , wherein the wrapping machine is configured to form the overlapping regions such that a reinforced edge of a first roll segment overlaps a reinforced edge of a second roll segment in an at least substantially parallel manner.

13. The roll of wrapping material of claim 10 , wherein the overlapping regions comprise at least four layers of film material.

14. The roll of wrapping material of claim 1 , wherein each first reinforced edge and each second reinforced edge comprises a hemmed edge.

15. The roll of wrapping material of claim 1 , wherein the plurality of roll segments comprises three roll segments.

16. The roll of wrapping material of claim 15 , wherein the plurality of roll segments comprises at least four roll segments.

17. The roll of wrapping material of claim 1 , wherein the roll of wrapping material comprises a length of between about 15 inches and about 40 inches.

18. The roll of wrapping material of claim 1 , wherein each of the plurality of roll segments comprises a length of between about 7.5 inches and about 15 inches.
