Abstract

A packaging material for protecting a packaged product is disclosed. The packaging material includes a core material having a plurality of cells with open tops and bottoms A first reinforcing layer covers the open tops of the cells of the core material. A second reinforcing layer covers the open bottoms of the cells of the core material. A layer of anti-abrasive material is attached to the first reinforcing layer. A second layer of anti-abrasive material may be attached to the second reinforcing layer. The packaging material may be formed into angle pads, corner pads and channel protectors also.

Claims

1. A packaging material, comprising:

a core material having a plurality of cells with open tops and bottoms;

a first reinforcing layer attached to the open tops of the cells of the core material;

a second reinforcing layer attached to the open bottoms of the cells of the core material; and

a first layer of anti-abrasive material attached to the first reinforcing layer.

2. The packaging material of claim 1, further comprising a second layer of anti-abrasive material attached to the second reinforcing layer.

3. The packaging material of claim 1, wherein the first layer of anti-abrasive material comprises a layer of tissue paper.

4. The packaging material of claim 1, wherein the first layer of anti-abrasive material comprises a layer of micro-foam.

5. The packaging material of claim 1, formed into a corner post

6. The packaging material of claim 1, formed into a channel protector.

7. The packaging material of claim 1, formed into an angle protector.

8. The packaging material of claim 1, wherein the first reinforcing layer is paperboard.

9. The packaging material of claim 8, wherein the first reinforcing layer is a single ply of paperboard.

10. The packaging material of claim 1, wherein the second reinforcing layer is paperboard.

11. The packaging material of claim 10, wherein the second reinforcing layer is a single ply of paperboard.

12. The packaging material of claim 1, wherein the core material is a honeycomb material having a plurality of hexagonal cells with open tops and bottoms;

13. A method of making an anti-abrasive packaging material, comprising:

providing a core material having a plurality of cells with open tops and bottoms;

attaching a first reinforcing layer onto the open tops of the cells of the core material;

attaching a second reinforcing layer onto the open bottoms of the cells of the core material; and

attaching a first layer of anti-abrasive material onto the first reinforcing layer.

14. The method of claim 13, further comprising attaching a second layer of anti-abrasive material onto the second reinforcing layer.

15. The method of claim 13, wherein the core material provided is a honeycomb material having a plurality of hexagonal cells with open tops and bottoms.

16. The method of claim 13, wherein said step of attaching a first reinforcing layer onto the open tops of the cells of the core material comprises attaching a single ply of paperboard onto the open tops of the cells of the core material.

17. The method of claim 13, wherein said step of attaching a second reinforcing layer onto the open bottoms of the cells of the core material comprises attaching a single ply of paperboard onto the open bottoms of the cells of the core material.

18. The method of claim 13, wherein said step of attaching a first layer of anti-abrasive material onto the first reinforcing layer comprises attaching a layer of tissue onto the first reinforcing layer.

19. The method of claim 13, wherein said step of attaching a first layer of anti-abrasive material onto the first reinforcing layer comprises attaching a layer of micro-foam onto the first reinforcing layer.
