<p>The invention relates to a packaging material in small pieces for filling cavities in solid packaging containers. The packaging material consists of an outer cover made of a coarse-pored, highly air-permeable, thin paper, such as e.g. baker's silk, which encloses a filling of paper waste (chips) from shredders or the like. The ball-like packaging containers of up to 10 cm diameter are folded or glued. The filling tends not to crumble, and all materials involved degrade easily. The packaging container is very elastic as a result of its air-permeability and adapts well to the hollow shapes to be filled.</p> |
