| Abstract: | The study is focused on the effect of collagen hydrolysate and glycerol on properties of water‐soluble polyvinylalcohol (PVA) blown films and blends. The experimental design method (DOE) was used in this study. Results from DOE show a strong effect of interactions between the blend components on resulting properties of the films. This fact was confirmed by means of the response surfaces of melting flow index, tensile strength and the content of insoluble fraction. It was concluded that the composition of PVA/CH blend must be precisely specified to avoid the processing complications. |
