Abstract: Provided herein are polymer films including a polyamide composition of PA6 and PA66/6. The provided films are particularly useful as packaging materials as they exhibit improved toughness, e.g., puncture and impact resistance, relative to that of conventional films that include only PA6 as a polyamide component. Also provided are methods for making the provided films, and articles that include the provided films.
