International audience; Poly(lactic acid) (PLA) films have a great interest for the food packaging. But the interaction between the food and the packaging must be investigated. The gas and aroma barrier properties of PLA were analysed and the influence of PLA crystallinity on these properties was studied because of processing conditions. The crystallinity seems to have no effect on helium and oxygen barrier properties but ethyl acetate as aroma compound has a plasticizing effect on the PLA film.
