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.
