Evaluation des impacts environnementaux des sacs de caisse Carrefour Eco-Bilan a division of PriceWaterhouseCoopers is noted worldwide for its expertise in life cycle analysis. InEco Bilan carried out a life cycle analysis on paper and plastic bags for Carrefour, a very large French retailer. The results were definitive — plastic is environmentally superior to paper.

August 15, through August 14, Project Amount: Packaging is one of the largest market segments for the polymer industry. Food packaging industry is currently dominated by crude oil-derived, non-biodegradable polyolefin and polyesters. Due to their environmental persistence non-biodegradability leading to accumulation in land and water, plastic packaging materials have come under intense scrutiny.
Thus there is an immediate need to develop bio-based, biodegradable plastic alternatives for food packaging. Although this sector is growing rapidly, bioplastic films do not have adequate barrier properties for being used directly in food packaging applications.
The goal of this research project is to develop and test a bio based packaging solution with significantly improved barrier properties especially to oxygen and water vapor. The objective of the proposed research effort is to develop novel coating formulations and appropriate processes to significantly enhance the gas barrier properties of bioderived polylactic acid PLA films.
The surface modification of PLA would be carried with the following considerations: The objectives of this research effort is to use biodegradable substrates such as polylactic acid as a potential food packaging material and to develop an optimal coating formulation to improve oxygen and water vapor barrier properties.
Ionically charged nano-clay increases tortuosity in the transport path, thereby reducing diffusion of any absorbed molecules through the films. Coating on both side of PLA reduces desorption of any molecules that might have diffused through the film.
Effect of each of the layers on oxygen and water vapor transmission will be studied. Chitosan, fatty acids and nano-clay layers are expected to substantially reduce the oxygen transmission and water vapor transmission rate through PLA films.
Effect of coatings on mechanical and optical properties of the films will also studied.
