Abstract
A biaxially oriented film includes a PLA and polyolefin (PLA/PO) blend. The film has a haze of 80% or greater as measured by ASTM-D1003 and a 45° gloss of less than 50% as measured by ASTM-D-2457.

A method of producing a biaxially oriented film comprising:
- blending a polylactic acid (PLA) and a polyolefin (PO) to form a polymeric blend (PLA/PO blend) having a ratio of PLA to PO in the PLA/PO blend between 4:1 and 199:1, wherein the polyolefin is a polyethylene,
- forming the PLA/PO blend into a film, and
- biaxially orienting the film to form a film having a haze of 80% or greater as measured by ASTM-D1003 and a 45° gloss of less than 50% as measured by ASTM-D-2457.
An article comprising:
- a polylactic acid (PLA) and polyolefin (PO) blend having a ratio of PLA to PO in the PLA/PO blend of between 4:1 and 199:1, wherein the polyolefin is a polyethylene, and wherein the article is opaque.
A blend comprising:
- a polylactic acid (PLA) and a polyolefin (PO), wherein the polyolefin is a polyethylene, and wherein the blend includes between 80 and 99.5 weight percent of the PLA.
