ABSTRACT:
A thermoplastic film is comprised of an admixture of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and a functional amount of a cellulose ester plasticizer. The film has an opacity in the range of 10 to 85 percent, a thickness in the range of 0.002 to 0.010 inch, a porosity in the range of 0.0 to 50 ml/min/cm.sup.2 at a 1.0 centibar pressure drop and a compostability of less than 65 days fragmentation. The film is prepared by making a paper comprised of 20 to 85 weight percent cellulose ester fibers and 80 to 15 weight percent cellulose fibers and saturating the paper with a functional amount of a cellulose ester plasticizer. The saturated paper is subjected to heat and pressure for a period of time to obtain the thermoplastic film. The thermoplastic film is prepared without the use of solvents and is economically attractive since it is compatible with conventional paper printing materials and techniques.
