- •
Influence of heating time in preparation of biodegradable film is performed.
- •
Thermal degradation of κ-carrageenan follows by a pseudo first-order kinetics.
- •
Introducing thermally treated κ-carrageenan into chitosan was reduced water resistance.
- •
Tensile strength of treated chitosan/κ-carrageenan was lower than the intact blend.
- •
Surface hydrophobicity of the blend film was found to be function of κ-carrageenan heating time.
