Embossed oriented thermoplastic films and methods of making them are described. The embossed oriented thermoplastic films have substantially the same mechanical properties as unembossed oriented thermoplastic films. The depth of the embossments ranges from about 1 μm to about 200 μm. The methods include providing an oriented thermoplastic film having first and second major surfaces, softening at least one of the first and second major surfaces to produce a softened surface, embossing the softened surface to produce an embossed oriented thermoplastic film, and cooling the embossed oriented thermoplastic film.
