Abstract
A process for producing polyolefin articles comprising an ethylene-vinyl alcohol copolymer, wherein the polyolefin component is melted and mixed with the ethylene-vinyl alcohol copolymer in the presence of a stabilizing composition comprising: a) one or more acid scavengers in amounts equal to or higher than 300 ppm by weight with respect to the weight of the polyolefin component; and b) one or more phenolic antioxidants in amounts equal to or higher than 1100 ppm by weight with respect to the weight of the polyolefin component.
