| Summary: | Pollution
is a global problem and the increased use non-biodegradable plastic packaging
films have caused environmental concerns. Thus, there is a tendency to use
natural polymer materials, such as biodegradable films. This paper aims to
prepare and characterize novel collagen hydrolysate/carboxymethyl
cellulose/nano-SiO2 films for packaging/coating applications. The
results indicate that the incorporation of nano-SiO2 in films from
1% to 4% caused significant increase (p<0.05) in thickness and tensile
strength but significantly decreased the elongation at break. Nano-SiO2
drastically reduced the water vapor permeability and water solubility values of
films. Furthermore, the increments in nano-SiO2 proportion in films
increased the values of transparency and provided a reduction in the light transmission
in the ultraviolet and visible range. This study demonstrates that nano-SiO2
addition to collagen hydrolysate/carboxymethyl cellulose films gives
significantly effects on properties of film produced. The enhancement of film
properties shows the potential for using collagen hydrolysate/carboxymethyl
cellulose films for coating/packaging purposes. |
