Abstract
The present invention concerns a cellulose based composition for manufacturing a film or foil, which composition comprises at least one selected from the group consisting of cellulose acetate butyrate, cellulose acetate propionate and ethyl cellulose, together with tall oil fatty acid ester, as well as a manufacturing method thereof. The invention also concerns packaging film comprising the composition and use of the composition.
Claims18
A cellulose based composition for manufacturing a film or foil, comprising
- a. at least one polymer selected from the group consisting of cellulose acetate butyrate, cellulose acetate propionate, and ethyl cellulose, and
- b. tall oil fatty acid ester,
- wherein the molar mass of said at least one polymer is above 20,000 Da, and wherein said composition comprises
- cellulose acetate butyrate in an amount of 10 to 80 weight-%,
- cellulose acetate propionate in an amount of 10 to 80 weight-%,
- ethyl cellulose in an amount of 0 to 90 weight-%, and
- tall oil fatty acid ester in an amount of 5 to 50 weight-%, based on the total weight of the composition.
