Expandable plastics granular material having at least one orifice

摘要

The invention relates to a plastics granular material of foamable particles which are derived from a star-shaped basic body with at least three limbs lying in a plane, the particles having at least one orifice. Preferably, these granular material particles are provided with three limbs and each limb is provided with an orifice. Furthermore, the invention has as its subject a packaging material which is obtained by foaming of the said plastics granular material. This packaging material displays a lower bulk density, improved pourability with simultaneously improved packing effect (good packaging properties, large void volume).
