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.
Claims15
An expandable slit sheet paper wrap cushioning product, comprising:
- a roll of expandable 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;
- said expandable slit sheet paper being formed from an extensible paper made to be extensible in the machine direction without said slit pattern, said extensible paper having an extensibility within a range of about 6.0-10.6% in the machine direction under JIS P8113:
- 2006;
- and
- said expandable slit sheet paper having a weight, prior to expansion, within a range of about 30-50 pounds per 3,000 sq. ft.,
- whereby a user can manually expand the extensible slit sheet paper, wrap the expanded expandable slit sheet paper around an object, and place the wrapped object within a shipping container with the expanded expandable slit sheet paper wrapped around the object for cushioning protection of the object within the shipping container.
