Abstract

Shock-absorbing biodegradable dunnage packaging material is obtained from recycling scrap paper by cooking the scrap paper in the presence of heated water to reduce the scrap paper to pulp fiber and then extruding the pulp fiber to thereby form the dunnage packaging material.

Claims

1. A package comprising an outer container having sides, at least one article within said outer container and free-flowing shock-absorbing biodegradable dunnage packaging material confined within said container wherein said packaging material is obtained by recycling scrap paper by cooking said scrap paper in the presence of heated water at a temperature and for a time sufficient to reduce the scrap paper to pulp fiber and then extruding the pulp fiber under pressure to thereby form said shock-absorbing biodegradable dunnage packaging material into pellet-like particles having desired size and shape, and wherein said shock-absorbing biodegradable dunnage packaging material is arranged in a haphazard relationship and closely packed around the article and holding the article in spaced relationship to the sides of the container.

2. The package of claim 1 wherein said scrap paper is scrap newspaper.

3. The package of claim 1 wherein said dunnage packaging material is about one-half (1/2) inch to about two (2) inches long and about one-quarter (1/4) inch to about three-quarters (3/4) inch in diameter.
