Abstract

A multi-layer film having a first film layer being at least partially formed from a polymer (A) and a polymer (B) and a second film layer being at least partially formed from the polymer (A), the polymer (B), a polymer (C), and optionally an opacifying agent, wherein at least one of the polymer (A), the polymer (B) and the polymer (C) is synthetic and is at least partially derived from a renewable resource such that the multi-layer film has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B. Methods of forming multi-layer films are also provided.
