tres and the initial concentration of ethylene was between 100-150 ppb. The surface of the films was 1,000 cm2. Using a septum, samples were taken at regular intervals in order to measure the concentration of ethylene. This was done under room temperature using a gas chromatograph. The reduction of the concentration after 24 hours of incubation was minimal. On the other hand, in commercially available packages of ethylene-absorbing bags of 5 grams, on the basis of potassium permanganate, no trac
