A series of interconnected packing chip precursors that can be formed and transported economically to a packager as a flat sheet and then expanded at the site where they will be used into individual packing chips by folding and separation from the other chips. Preferably, the precursors are formed on a chipboard sheet by forming fold lines and lines of separation and by adding securing means, such as bonding media or connecting features to secure the sides of the expanded packing chip in its final shape. The fold lines and lines of separation can be configured to form jagged or serrated edges on the expand-on-site packing chip, and the chip may also include apertures; the jagged and serrated edges and the apertures cooperating with each other and other aspects of adjacent chips to interlock the chips when they are placed around an item in a package for shipment.

1. A packing chip formed from a flat intermediate sheet containing two or more precursors, said chip comprising:sides configured so that the packing chip has a triangular cross-section;securing means for securing the sides of the chip in a final shape; andone or more apertures on at least one side configured such that the packing chip forms interlocking engagement with portions of adjacent packing chips when employed as packaging. 2. The packing chip of claim 1 wherein one or more sides are configured to form serrated edges or spines on the packing chip for interlocking engagement with apertures of adjacent packing chips when employed as packaging. 3. The packing chip of claim 1 wherein the sheet is made of chipboard. 4. The packing chip of claim 1 wherein the securing means comprises bonding media. 5. The packing chip of claim 4 Wherein the bonding media is an adhesive selected from the group consisting of thermosetting, microwave-activated, ultrasonic-activated, wettable or pressure activated adhesive. 6. The packing chip of claim 1 wherein the securing means comprises connecting features. 7. The intermediate sheet of claim 6 wherein the connecting features are selected from the group consisting of dovetail slots and grooves, tongue and groove cuts, hook cuts and combinations thereof. 8. An intermediate sheet of two or more packing chip precursors, each chip precursor being separably connected to at least one adjacent chip precursor and the precursor further comprising:three sections each of which is foldably attached to at least one other section which sections upon folding each form a side of the packing chip; andsecuring means for securing the sides of the packing chip in a completed shape selected from the group consisting of bonding media or connecting features, said shape having a triangular cross-section; andwherein the chip precursor contains one or more apertures on at least one section configured such that the expanded packing chip forms interlocking engagement with portions of adjacent packing chips when employed as packaging. 9. The intermediate sheet of claim 8 wherein the chip precursor contains one or more sides configured to form serrated edges or spines on the expanded packing for interlocking engagement with apertures of adjacent packing chips when employed as packaging. 10. The intermediate sheet of claim 8 wherein the sheet is made of chipboard. 11. The intermediate sheet of claim 8 wherein the securing means comprises bonding media. 12. The intermediate sheet of claim 11 wherein the bonding media is an adhesive selected from the group consisting of thermosetting, microwave-activated, ultrasonic-activated, wettable or pressure activated adhesive. 13. The intermediate sheet of claim 8 wherein the securing means comprises connecting features. 14. The intermediate sheet of claim 13 wherein the connecting features are selected from the group consisting of dovetail slots and grooves, tongue and groove cuts, hook cuts and combinations thereof. 15. The intermediate sheet of claim 8 wherein the sheet is rolled. 16. The intermediate sheet of claim 8 wherein the sheet is fan folded. 17. A method for forming an intermediate sheet of two or more packing chip precursors comprising:forming lines of separation to separably connect each chip precursor to the adjacent chip precursors on said intermediate sheet;forming three sections on each chip precursor by creating fold lines between adjacent sections, said sections each forming a side of the packing chip when expanded from the chip precursors;adding one or more securing means for securing the sides of the packing chip in a final form when expanded selected from the group consisting of bonding media and connecting features, said form having a triangular cross-section; andadding one or more apertures on at least one section of the packing chip precursor, said aperture being configured such that the expanded packing chip forms interlocking engagement with portions of adj acent packing chips when employed as packaging. 18. The method of claim 17 which further includes the step of configuring one or more sides on the sections to form serrated edges or spines on the expanded packing chip for interlocking engagement with one or more apertures of adjacent packing chips when employed as packaging. 19. The method of claim 17 in which the intermediate sheet is made of chipboard. 20. The method of claim 17 in which the securing means comprises bonding media. 21. The method of claim 20 wherein the bonding media is an adhesive selected from the group consisting of thermosetting, microwave-activated, ultrasonic-activated, wettable or pressure activated adhesive. 22. The method of claim 17 in which the securing means comprises connecting features. 23. The method of claim 22 wherein the connecting features are selected from the group consisting of dovetail slots and grooves, tongue and groove cuts, hook cuts and combinations thereof. 24. The method of claim 17 further comprising forming the sheet into a roll. 25. The method of claim 17 further comprising fan folding of the sheet. 26. A method for forming an expand-on-site packing chip from an intermediate sheet containing two or more chip precursors comprising:folding the precursor into three sections each of which forms a side of the expanded packing chip, said chip having a triangular cross-section;attaching the sides of the expanded packing chip; andseparating the expanded chip from the adjacent chip or chips. 27. The method of claim 26 in which the separating occurs prior to the folding. 28. The method of claim 26 in which the attaching is accomplished at least in part with connecting features. 29. The method of claim 28 wherein the connecting features are selected from the group consisting of dovetail slots and grooves, tongue and groove cuts, hook cuts and combinations thereof. 30. The method of claim 26 in which the attaching is accomplished with at least in part with bonding media. 31. The packing chip of claim 27 wherein the bonding media is an adhesive selected from the group consisting of thermosetting, microwave-activated, ultrasonic-activated, wettable or pressure activated adhesive. 32. A one-piece packing chip having an essentially triangular cross-section formed by three sides wherein:at least one side contains one or more aperturesat least one side contains a serrated edge or spine for engagement with serrated edges or apertures on adjacent packing chips when employed as packaging, andsecuring means for securing sides of the expanded packing chip. 33.
