Low density polyethylene or polyolefin films were used to seal pack various varieties of peaches and nectarines. Low density polyethylene film of 40 micron thickness was beneficial in extending storage life of these fruits and decreasing internal flesh breakdown and reddening, while polyolefin film was ineffective. Six fruits per pack generated a higher CO2 and lower O2 modified atmosphere than two or four fruits per pack and gave better quality fruit after storage. The improvement of fruit quality was correlated with elevated CO2 levels rather than with decreased O2 levels.
