  • Chitosan coatings applied to polyethylene surface to obtain food-packaging materials : static and dynamic viscoelastic properties
    Munteanu, Bogdǎnel Silvestru ...
    This paper deals with the optimization of the experimental conditions used for coating of polyethylene (PE) with chitosan, a nontoxic cationic polysaccharide, approved by the Food and Drug ... Administration (FDA) Agency, with good antimicrobial and biocompatibility properties. To enhance chitosan adhesion, the PE surface was previously corona treated. The uncoated and chitosan-coated polyethylene films were characterized by ATR-FTIR spectroscopy, X-ray photoelectron spectroscopy (XPS), potentiometric titration and scanning electron microscopy (SEM). The chitosan-coated PE films were also examined for oxygen permeability and antimicrobial activity against food pathogen microorganisms as Gram-positive (Listeria monocytogenes) or Gram-negative (Escherichia coli, Salmonella) bacteria.
