Benefits of technology

[0020]Accordingly, two slit sheets are maintained separated from each other at the initial region of the expansion where it is vital for the cells to open as a result of the wedge effect of the tool as disclosed in co-pending application Ser. No. 14/480,319. After the cells have expanded to an extent that is sufficient to resist reversal, the two slit sheets are positioned adjacent to each other in an interlocking relationship.
[0021]In an alternate embodiment, adjacent layers have diff

[0073]The first slit sheet pattern creates a ¼″ tall lead wall with each hexagonal side approximately being 3 / 16″ long. The second slit sheet pattern is also ¼″ tall by using the ⅛″ row spacing. The legs of the cell are approximately 10-30% less or more to create an interlocking composite product. In this case the preferred size would be 4″ slit×0.15″ un-slit creating a cell that will be 20% smaller than the first slit sheet pattern.

[0074]The second expanded slit sheet pattern creates a cell that easily could fit inside the first expanded slit sheet material but is inhibited by the increase in quantity of the smaller cell size causing a miss-match of cells trying to fit within each other.

[0075]In order for the operator to receive both slit sheet expanded materials at the same speed a special expander is required. The first expanded sheet layer expands from 1″ to approximately 2⅛″ inches depending upon paper strength and thickness. In the present invention the 60 pound basis weight p...

Abstract

A paper product comprised of two or more slit material layers, each layer having a pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. The layers having differing slit patterns that produce when expanded, inclined land areas that having different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.

Description

FIELD OF THE INVENTION[0001]This invention relates to an expander for a paper packaging material that is slit, expanded and layered around an object or used as a void fill.DESCRIPTION OF THE PRIOR ART[0002]There are a small number of in-the-box wrapping products found in the market today used to fill the open area within a box that is unused by the item being shipped. Wrappng an item to be shipped puts a barrier between it and the box. It also creates a larger cubic area as it sits within an adjacent void-fill product such as Styrofoam peanuts. The larger cubic area cushions as well as inhibits migration of the item to the sides of the package.[0003]Pleated Paper of U.S. Pat. No. 6,871,480 teaches using pleated paper laminated or layered on one or more layers of tissue paper as a cushioning product. The pleat height, paper fiber length, and number of pleats per foot, provide a cushioning product that crushes as force is applied. This application teaches the use of pleated paper as a...
