Abstract:
In this study, the use of nanocomposite polyethylene films to extend shelf life of food products and to enhance its barrier and mechanical properties was investigated. Nanocomposite was designated 80% wt LLDPE, 14.28% wt PE-g-MA, and 5.72% wt organoclay and package films were prepared on the "cast-film" line. The physical and chemical properties of these films were determined and evaluated. The results showed that an "exfoliated/intercalated" mixture was obtained, with un pronounced change in mechanical properties and transparencies, while oxygen permeability is decreased by 42% and the shelf-lives of foods extended up to twofold.
