<p>A thermoplastic film composition that includes a polymer blend of multiple inherently incompatible polymer components is described. The composition includes a polymer blend having about 5 wt.% to about 45 wt.% of a plasticized natural polymer, about 5 wt.% to about 40 wt.% of a polyolefin, a biodegradable polymer, and a compatibilizer with both a polar and a non-polar moiety on the same polymer molecule. The total plasticized natural and biodegradable polymers constitute a majority or predominant phase (â ¥ 51 wt.%), while petroleum-based olefinic polymers form the minority phase. The composition can be made into a film containing at least one renewable, natural polymer component. Also described are the articles of manufacture that may use such films.</p> |
