Abstract
The biaxially oriented film based on a propylene polymer contains an inorganic particulate neutralizing agent, in particular a carbonate or magnesium oxide. To improve the slip properties, the particles have been given a hydrophobic coating, in particular a coating of wax, a fatty acid, a salt of a fatty acid or an ester of a fatty acid.
