Three kinds of monolayer films were obtained by melt blending
and subsequent compression molding: thermoplastic starch
(S), thermoplastic starch with 5% (g/100 g of starch) PCL (S95) and
pure PCL (PCL). To prepare S films, native starch and glycerol were
dispersed in water using a starch:glycerol:water ratio of 1:0.3:0.5
(w/w). When starch films contained PCL,this was added to aqueous
dispersions in 1:0.05, w/w starch:PCL ratio
