Abstract

An oriented film composed of thermoplastic polymers is described which comprises at least one vacuole-containing layer. The vacuole-containing layer comprises particulate hollow bodies which are essentially composed of a polymer which is incompatible with the thermoplastic polymer. A process for producing the film is also described.
