It is also noteworthy that the rate of light transmittance at280 nm was markedly lower when compared with those displayed by some conventional polymer films i.e., 71.78–27.64%, for oriented polypropylene (OPP), and LDPE, respectively (Guerrero et al., 2011).These results suggest that prepared biocomposite films could be able to delay lipid oxidation caused by UV light in food systems. Invisible range, essential oil loaded films exhibited the better barrier attribute for light transmission. The results revealed that essential oils were capable to hinder the light transmission over the film.According to Tongnuanchan et al. (2012) the reduced light transmission was probably due to the light scattering at the interface of oil droplets inserted in the polymer matrix.
