Abstract Chitosan (CH) and low-density polyethylene (PE) blend films were produced by a twin-screw
extruder and heat press with different plasticizers glycerol (GLY), sorbitol (SOR) and polyethylene
glycol (PEG). The tensile strength decreased and elongation at break increased with the
incorporation of plasticizer for blends with 10 wt% of CH. The thermal stability of the films was
slightly higher for films containing GLY and PEG as compared to SOR. Contact angles reduced
from CH-PE film to the films containing PEG, SOR and GLY in decreasing order, respectively.
Fourier transform infrared spectroscopy revealed no interactions between CH and PE in CH-PE
film… More >
