Abstract
An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.
Claims28
A void fill slit sheet extensible paper cushioning product, comprising:
- a slit sheet extensible paper having a slit pattern including a plurality of slits extending in a cross direction that form open cells upon expansion in a machine direction,
- wherein extensibility of unslit extensible paper from which said slit sheet extensible paper is made is within a range from 9 to 20% in the machine direction.
A shipping package, comprising:
- a shipping container adapted to receive an object to be cushioned, said object being cushioned by an expanded length of a void fill slit sheet extensible paper, wherein:
- the void fill slit sheet extensible paper comprises a slit pattern including a plurality of slits extending in a cross direction that form open cells upon expansion in a machine direction, and
- extensibility of unslit extensible paper from which the void fill slit sheet extensible paper is made is within a range from 9 to 20% in the machine direction.
