Abstract
Abstract This study aimed to prepare and characterize the mechanical and physical properties of chicken skin gelatin/CMC composite film. The influence of CMC on the mechanical (tensile strength (TS), elongation at break (EAB), puncture test), physical (water vapour permeability (WVP), FTIR, X-ray diffraction (XRD), light transmission and transparency), and thermal properties (melting point, T m and glass transition, T g ) of chicken skin gelatin film were studied and compared to bovine gelatin film. Results shows that chicken skin gelatin/CMC composite films was higher in TS, puncture force, WVP, and T g value. However, there were no significance different (p > 0.05) between chicken skin gelatin as compared to bovine gelatin film in TS and WVP value. This study demonstrates that a CMC addition to gelatin films gives significantly effects on properties of film produced. The enhancement of film properties shows potential for using this blended film in packaging materials or coatings in agriculture and food products.
