Description	B-starch or acetylated starch prepared from it, with the degree of substitution (DS) of 1.5–2.3, was used in biodegradable films after blending with poly-(ε-caprolactone) (PCL). Mechanical characteristics (Young modulus, yield stress, stress-at-break) were determined on the produced films. Water absorption of PCL/starch (60/40) films was determined according to standard ISO 62. The films containing native starch degraded in compost totally during 2 months. Acetylation of starch molecules in the composites reduced the degradation rate. Optical microscopy, in combination with the image analysis system NIS-Elements vs. 2.10 completed with an Extended Depth of Focus (EDF) module, was used to study the surface morphology of PCL/starch films after 20-day and 42-day compost incubation. Chemical changes in the compost used for the film exposition were measured.
