Abstract

An inflatable packaging element is disclosed herein. The inflatable packaging element includes a first film ply and second film ply overlayed on the first ply, and a seal pattern. The seal pattern has a plurality of seals sealing the first and second plies to each other to define an inflation chamber between the first and second plies. The inflation chamber is inflatable with and configured to contain a fluid. An aperture extends through at least one of the first or second ply, and the seal pattern separates opposite side of the aperture from the inflation chamber.

First claim

What is claimed is:

1. A continuous web of inflatable protective packaging elements, comprising:
a first ply; and
a second ply overlaid on the first ply to define a plurality of connected inflatable protective packaging elements;
wherein the first and second plies are sealed together along a seal pattern in each of the protective packaging elements, the seal pattern defining one or more inflation chambers between the first and second plies, which one or more inflation chambers are inflatable with, and configured to, contain a fluid;
wherein a line of perforations extends through the first and second plies providing a separable boundary between first and second inflatable protective packaging elements of the plurality of connected inflatable protective packaging elements, the line of perforations being configured to reduce tearing forces to facilitate tearing the first protective packaging element from the second protective packaging element; and
wherein the first and second plies define a handle disposed longitudinally adjacent the separable boundary, which handle is configured and dimensioned to receive a user's fingers through the first and second plies.

2. The continuous web of claim 1 , wherein the separable boundary comprises a plurality of separable boundaries extending transversely across the web periodically between adjacent ones of the inflation chambers.

3. The continuous web of claim 1 , wherein the handle defines an opening dimensioned to receive the user's fingers through the first and second plies.

4. The continuous web of claim 1 , wherein the handle defines another line of perforations disposed along an edge of the handle, the another line of perforations being configured to break and provide an opening dimensioned to receive the user's fingers through the first and second plies.

5. The continuous web of claim 4 , wherein the another line of perforations at least partially surrounds and area of the plies that will provide the opening when the line of perforations is broken.

6. The continuous web of claim 5 , wherein the first and second plies include a cut that provides an aperture through which the user's fingers can be inserted.

7. The continuous web of claim 1 , wherein the seal pattern includes a handle seal that separates the handle from the one or more inflation chambers.

8. The continuous web of claim 1 , wherein the seal pattern includes a handle seal that separates the handle from the separable boundary.

9. The continuous web of claim 1 , wherein the seal pattern includes a handle seal that surrounds the handle.

10. The continuous web of claim 1 , wherein the handle is proximal to the transverse end of each inflatable protective packaging element.

11. The continuous web of claim 1 , wherein the continuous web is rolled into a roll configuration.

12. The continuous web of claim 1 , wherein the continuous web includes opposite transverse sides, and the separable boundary extends transversely across the web from one transverse side of the web to the other.

13. The continuous web of claim 1 , wherein the continuous web is disposed in a fan-fold configuration.

14. The continuous web of claim 13 , wherein the handle is elongated transversely with respect to the web.

15. The continuous web of claim 13 , wherein the handle is parallel to the separable boundary.

16. The continuous web of claim 1 , wherein the handle is disposed between the separable boundary and one of the inflation chambers.

17. The continuous web of claim 1 , further comprising a longitudinal inflation region wherein inflation of the longitudinal inflation region causes inflation of the one or more inflation chambers.

18. The continuous web of claim 17 , wherein the longitudinal inflation region comprises an inflation channel that has a substantially or entirely closed periphery about its longitudinal axis.

19. A protective packaging system, comprising:
the continuous web of claim 1 ;
an inflation and sealing device, including:
an inflation mechanism operable to inflate the web with a fluid by directing the fluid between the first and second plies of the web as the continuous web advances along the material path;
a sealing mechanism to seal the plies together to seal the fluid therein.

20. The protective packaging system of claim 19 , wherein the fluid is air.

21. The protective packaging system of claim 19 , further comprising a bulk material support configured to support the continuous web prior to entering the device and configured to direct the web into the device.

22. The protective packaging system of claim 19 , wherein the inflation and sealing device is configured to advance the web along a material path.

23. The protective packaging system of claim 19 , wherein the inflation and sealing device comprise an inflation nozzle and cutting device, wherein the inflation nozzle is configured to blow gas between the plies and the cutting device is configured to cut the web off the inflation nozzle.

24. The continuous web of claim 1 , wherein the plies include a heat sealable polymer such that the plies are heat sealable to each other to seal the inflation chambers to contain the fluid.

25. A method of producing a plurality of inflated protective packaging elements separated by a plurality of separable boundaries, comprising:
inflating the protective packaging elements by inflating, with a fluid, a plurality of connected inflation chambers of a continuous web, the inflation chambers being disposed between first and second plies of the continuous web, wherein a plurality of lines of perforations extend through the first and second plies providing the plurality of separable boundaries extending transversely across the web periodically between adjacent ones of the inflation chambers;
forming a seal between the first and second plies adjacent the inflated inflatable chambers to seal closed and retain the fluid in the inflated inflation chambers;
inserting a user's fingers into a handle through the first and second plies, the handle disposed longitudinally adjacent one of the plurality of separable boundaries; and
tearing an inflated protective packaging element from a remainder of the web at the one of the plurality of separable boundaries by pulling on the handle with the user's fingers inserted therein, such that the torn off inflated protective packaging element includes at least one of the inflated inflation chambers.

26. The method of claim 25 , wherein the seal is formed using a heating element.

27. The method of claim 25 , wherein the heating element is configured to maintain a temperature that is sufficient to seal the overlapping portions of the first and second plies to each other.

28. The method of claim 25 , wherein the continuous web includes opposite transverse sides, and the plurality of separable boundaries extend transversely across the web from one transverse side of the web to the other.
