AbstractThe aim of this study was to evaluate ethylene permeation through a food packaging‐grade polyvinyl chloride at 3,10,17 and 25°C. The transmission rates were calculated to estimate the permeability (P) at these temperatures. This permeability is influenced by the temperature, giving values from 120 000cm3μm/m2. d atm at 3°C to 367000cm3μm/m2.datm at 25°C. Other parameters, such as the selectivity factor (p), the temperature coefficient (Q10) and the activation energy (Ea). were compared to values obtained for other gases (O2and CO2) using the same film and su
