Abstract
In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

A slit sheet paper cushioning product, comprising:
- a slit sheet paper having a slit pattern including a plurality of slits extending in a cross direction that forms a plurality of open cells upon expansion in a machine direction,
- wherein each of said plurality of slits are straight slits and wherein each of said straight slits extends substantially parallel to the cross direction,
- wherein the slit width of each of said straight slits in the cross direction is less than 0.35 inches, and
- wherein said slit sheet paper is formed from a recyclable paper having a weight, prior to expansion, of at least 30 pounds per 3,000 square feet.
