ABSTRACT:
The invention relates to plastics granules composed of foamable particles derived from a star-shaped fundamental solid having at least three sides, these particles being a three-dimensionally domed structure by virtue of the sides having paraboloidal curvature, and the surfaces of paraboloidal curvature being staggered in relation to one another. These granule particles preferably have three sides and at least one gap.
The invention also relates to a packaging material obtained by foaming the said plastics granules. This packaging material exhibits an improved flow while having at the same time an improved packaging action (good packaging properties and a high void volume).
