Abstract
A plastics material with at least first and second layers of plastic polymeric material, the material of the first layer having a melting point lower than the melting point of the material of the second layer. The layers are orientated and heated to at least the melting point of the first layer so that the first layer breaks up to form an irregular surface pattern bonded to the second layer. A method of producing the plastics material is also provided, the orientation and heating being done sequentially or simultaneously. The material has cloth-like properties with a "soft" feel and with minimal noise.
