| 摘要 |
<p>The present invention comprises an apparatus and method for producing a biodegradable, thin-walled packing chip (20) from an aqueous pulp of recycled newsprint by contacting the pulp with a mold (40) comprising: (a) a solid core (41) having substantially the shape of the article to be formed and having a minimal number of holes through which air may be evacuated and (b) an air permeable, stretchable fabric (60) which covers the exterior of the core. After forming the chip (20) on the fabric through application of a vacuum, the fabric is separated sufficiently from the solid surface to cause release of the chip from the fabric (60). The dried packing chip has enhanced packing qualities, is environmentally friendly and provides a significant new use for recycled newsprint.</p> |
