The modern society is facing environmental concerns about the exploitation and use of petroleum-based polymers in terms of their degadation rate and subsequent solid waste issues. As traditional treatment technologies cannot response to the appropriate extent, scientific effort has been focused towards novel recycling technologies as well as development of potential substitutes for conventional plastic. In these sense, polyhydroxyalkanoates (PHA) presenting biobased and biodegradable polyesters produced by microbial fermentation has been extensively studied as a promising replacement. With regards to their practical interest and potential contribution in various fields of biomedicine, packaging, electronic devices, the demand for specific mechanical and thermal requirements is expanding. The aim of this study is related to overcome the main constrictions of polyhydroxyalkanoates - their high brittleness and narrow thermal processing window. Poly(3- hydroxybutyrate-co-3-hydroxyvalerate) and poly(caprolactone diol) blends were prepared via practical and cost-effective solution casting method. Thermal, structural mechanical and surface properties of the obtained thin films were thoroughly evaluated by FTIR, DSC, SEM and by investigating their tensile properties together with wettability
