Connective protective packaging

1. A chain of packaging elements in a high-density supply configuration that is configurable into a low-density configuration for protective package cushioning, comprising a plurality of connected packaging elements having a first surface and a second surface, each connected packaging element having a separation region extending therebetween to allow separation of the connected packaging elements, wherein:

each connected packaging element of the connected packaging elements has a bonding element on an exposed surface thereof;

the bonding element is configured to operably bond the exposed surface to an abutting surface by contacting the abutting surface with the bonding element when the respective packaging element is in a low-density configuration;

each of the packaging elements has a release surface of a material adapted to release any of the bonding element in contact therewith so that the bonding element can thereafter bond strongly to the abutting surface; and

the packaging elements are arranged in the high-density supply configuration in which successive layers of the connected packaging elements are placed onto each other, with the bonding elements of the packaging elements in contact with the release surfaces of others of the packaging elements such that the connected packaging elements can be taken out of the high-density supply configuration so that the released bonding elements can thereafter attach the packaging elements to the abutting surface.

2. The chain of packaging elements of claim 1 , wherein the plurality of connected packaging elements in the high-density supply configuration are configured as a roll having the successive layers, in which the first surface of the of each layer abuts the second surface of a subsequent layer.

3. The chain of packaging elements of claim 2 , wherein:

the bonding element is disposed on the first surface; and

the release area is disposed on the second surface.

4. The chain of packaging elements of claim 1 , wherein the connected packaging elements in the high-density supply configuration are fanfolded by a plurality of fan folds into a fanfold configuration having the successive layers, in which the first surface of each layer is disposed on the first surface of a subsequent layer, and the second surface of each layer is disposed on the second surface of the subsequent layer.

5. The chain of packaging elements of claim 4 , wherein the connected packaging elements in the high-density supply configuration are fanfolded at the separation regions.

6. The chain of packaging elements of claim 4 , wherein one or both of the first and second surfaces have a pattern of release areas and bonding elements disposed to contact each other in the fanfold configuration.

7. The chain of packaging elements of claim 4 , comprising an alternating series of bonding elements and release areas on each of the first and second surface.

8. The chain of packaging elements of claim 7 , wherein the alternating bonding elements and release areas alternate at each fan fold.

9. The chain of packaging elements of claim 7 , wherein the alternating series also alternates on the opposite surface, such that a region between each fan fold includes the bonding element on one of the first and second surface and the release area on the other of the first and second surface.

10. The chain of packaging elements of claim 4 , wherein each region between the fan folds has the bonding element on each of the first and second surface or the release area on each of the first and second surface.

11. The chain of packaging elements of claim 4 , the fan folds are disposed between each connected packaging element.

12. The chain of packaging elements of claim 1 , wherein each bonding element is a cohesive sticking element including a cohesive substance.

13. The chain of packaging elements of claim 1 , wherein each release area is not a complementary cohesive substance.

14. The chain of packaging elements of claim 1 , wherein:

the connected packaging elements comprise a web having a first ply and a second ply overlapping the first ply, the first ply and the second ply being connected together to define therebetween a fillable chamber to contain a filler element that separates the first ply and the second ply in the low-density configuration; and

the first ply including the exposed surface with the bonding element.

15. The chain of packaging elements of claim 14 , wherein the first ply and the second ply are connected together to trap a fluid therebetween when sealed, such that each of the connected packaging elements is an inflatable cushion.

16. The chain of packaging elements of claim 15 , wherein the fluid is air, and wherein the first ply and the second ply are connected together by an airtight seal.

17. The chain of packaging elements of claim 1 , wherein the connected packaging elements are foam-in-bag cushions.

18. The chain of packaging elements of claim 1 , wherein the connected packaging elements are paper dunnage.

19. The chain of packaging elements of claim 1 , wherein the abutting surface is a surface of a product.

20. The chain of packaging elements of claim 1 , wherein the abutting surface is an interior surface of a container in which the connected protective packaging element is received, wherein each bonding element bonds to the interior surface to retain the connected packaging element in a position against the container while a product to be protected is being packaged.
