Zusammenfassung:	A blend, multilayer film and process for making a multilayer film having improved processability and lower crystallization temperature is disclosed. The blend being at least 90.0% ethylene vinyl alcohol copolymer having a first crystallization temperature; and between (i) processing aid as compared to the barrier layer. The blend having a second crystallization temperature that is at least lower than the first crystallization temperature. L'invention concerne un mélange, un film multicouche et un procédé de fabrication d'un film multicouche ayant une aptitude au traitement améliorée et une température de cristallisation inférieure. Le mélange est constitué d'au moins 90,0 % de copolymère d'éthylène-alcool vinylique ayant une première température de cristallisation ; et entre (i) un adjuvant de traitement par rapport à la couche barrière. Le mélange présente une seconde température de cristallisation qui est au moins inférieure à la première température de cristallisation.
