Multi-layer films and methods of forming same

A multi-layer film comprising:

• a) a first film layer having an upper surface and a lower surface, the first film layer being at least partially formed from a polymer (A) and a polymer (B), wherein the first film layer comprises from about 75% to about 99% by weight of the polymer (A) and from about 1% to about 25% by weight of the polymer (B), wherein the polymer (A) comprises at least one of a low density polyethylene (LDPE) and a linear low density polyethylene (LLDPE) and the polymer (B) comprises a copolymer;
• b) a second film layer at least partially overlying one of the upper surface and the lower surface of the first film layer, the second film layer being at least partially formed from the polymer (A), the polymer (B), a polymer (C), and optionally an opacifying agent, wherein the polymer (C) comprises a homo polypropylene (homo-PP), and wherein at least one of the polymer (A), the polymer (B) and the polymer (C) comprises a polyolefin whose precursor monomers were at least partially derived from a renewable resource selected from the group consisting of plants, animals, fish, bacteria, fungi, and forestry products;
• and
• c) a bio-based content of about 10% to about 100%, wherein the bio-based content is the percent mass of organic carbon in the multi-layer film at the exclusion of carbon from inorganic sources using ASTM D6866-10, method B.
