Description	Native or pre-gelatinized wheat starches (A and B types) or acetylated derivatives or native starch with degree of substitution DS of 1.52.3 (10, 20, and 40 % m/m) were blended with poly-(ε-caprolactone) (PCL). Structure of the prepared films was analysed by FT-IR spectroscopy in comparison with the initial polymers. The following mechanical characteristics of the prepared films were derived from the stress-strain curves: Young modulus, yield stress, tensile strength, and strain at break. Water absorption of PCL/starch (6O/4O) films was determined according to ISO 62. The films containing native and pregelatinized starch degraded in compost totally during 1-2 months. Acetylation of starch molecules in the blends reduced the degradation rate. Chemical changes in the compost used for film exposition were measured.
