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 DEG C b) permeability for carbon dioxide is at least 600 cc.mm/m2.day.atm at 10 DEG 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 DEG 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.
