Abstract: The present invention relates to the use of a packaging material in the construction of a container for respiring produce, wherein the packaging material consists of a polyether-ester block copolymer or a blend of polyether-ester block copolymers and which packaging material has all of the following properties: a) permeability for oxygen is at least 40 cc.mm/m2.day.atm at 10° C. b) permeability for carbon dioxide is at least 600 cc.mm/m2.day.atm at 10° C. c) perm selectivity of carbon dioxide to oxygen is at least 10 d) water vapour transmission is at least 0.5 g.mm/m2.day at 10° C. and 85% RH and e) wherein the dimensions of the packaging material are chosen so as to allow oxygen to enter into the container at a rate lower than 110% of the respiration rate of the produce The invention also relates to a container made from the packaging material.

Abstract: Oxygen scavenging composition comprising a copolymer comprising polypropylene oxide segments and polymer segments and an oxidation catalyst, characterized in that the copolymer has been prepared by copolymerising the corresponding monomers in the presence of functionalised polypropylene oxide segments and process for the preparation of this composition.
