Abstract

A hollow article (e.g. a bottle) made of a biaxially oriented thermoplastic is produced by heating a sheet of thermoplastic material (12) to a temperature above its orientation temperature; forcing the heated sheet by pressure into a first mold half (20); maintaining the sheet in contact with the surface of the mould half (20) to allow the sheet to reach its orientation temperature, and then forcing the sheet into the second mold half (18) by means of pressure. <IMAGE>
