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 but, the addition of each plasticizer caused an interaction between CH and the plasticizer.
CH-PE film containing PEG showed the smallest water vapor permeability. The heterogeneous
structure of CH-PE film was improved with the addition of each plasticizer.CH-PE film containing
SOR underwent biodegradation rate at a faster compared to the films containing GLY and PEG
in soil burial end of 120 days.The lowest biodegradation rate was obtained in CH-PE film
containing PEG, among the plasticized-films.},
