For making a monolayer packaging article having O.sub.2 scavenging properties, a dry blend is prepared by dry blending: --(A) polyamide pellets (A1) coated with at least one first transition metal catalyst (A2),--preferably (B) a second transition metal catalyst and--(C) a polyester, and the dry blend (A/C) or (A/B/C) is processed in order to form the monolayer packaging article. Preferably, the amount of (A) is between 1 wt % and 4 wt % of the total weight of the dry blend [(A/C) or (A/B/C)], and the total amount of the first (A2) and where appropriate second (B) transition metal catalysts is between 1 wt % and 15 wt % of the total weight of polyamide pellets (A1).
