Respiration and weight loss rate, and gaseous composition inside the packaging of mangos cv. Keitt individually sealed in a low-density polyethylene film, 24.5 _m thick, stored at 7°C (80-90% RH); 12°C (75-85% RH); 17°C (70-80% RH); 22°C (65-75% RH) e 25°C (65-75% RH) were determinated. After mass transfer had reached a steady state, mango peel permeability to water vapor and concentration of carbon dioxide inside the packaging were calculated using experimental results and mass transfer equations. Calculated peel permeability was 600 times greater than plastic film. Experimental and calculated carbon dioxide concentration were compared and, according temperature, were founded differences between -16% and 29%.
