| abstract |
The invention discloses a thermoplastic film composition containing a polymer mixture composed of a plurality of polymer components which are essentially incompatible, wherein the polymer mixture contained in the composition is composed of about 5-45 wt% of natural plasticizing polymer, about 5-40 wt% of polyolefine, biodegradable polymer, and a compatibilizer which simultaneously has a polar part and a nonpolar part on one polymer molecule; and the natural plasticizing polymer and the biodegradable polymer form a major phase or dominant phase (>=51 wt%), and the petroleum-base olefinic polymer forms a minor phase. The composition can be made into a film containing at least one renewable natural polymer component. The invention also discloses a product which can be made of the film. |
