This work presents the development of a method to measure the ethylene permeability of plastic films used in vegetable packaging, by exploiting the adsorption and desorption properties of a synthetic sodium zeolite. In order to establish the best conditions and requirements for the procedure, the ethylene adsorption and desorption by the zeolite was studied at different temperatures and partial pressures. The method was used to study the ethylene permeability of two common cling films (EVA and plasticized PVC) and shown to be both economical and accurate.
