SHEET‑MATERIAL COMPOSITE, USE OF THE SHEET‑MATERIAL COMPOSITE AND CREPE SHEET CONTAINING THE SHEET‑MATERIAL COMPOSITE

摘要

The invention specifies a sheet‑material composite which comprises a first outer layer (10), a second outer layer (20) and a first central layer (30) between the first and second outer layers (10, 20). The first and/or second outer layers (10, 20) may have components which comprise at least one polyolefin, a component selected from a group comprising microspheres, polystyrene and ultra high molecular weight polyethylene, and also a polymer having a lower melting point than the rest of the components of the first and/or second outer layers.
