The permeabilities of two commercial ceramic‐filled LDPE films were measured and compared with those of a plain LDPE film. The ceramic films have higher oxygen (0 2 ), carbon dioxide (CO 2 ) and ethylene (C 2 H 4 ) permeabilities, higher CO 2 to O 2 permeability ratio, and higher C 2 H 4 to 0 2 permeability ratio. The temperature dependence of the permeability was found to follow the Arrhenius relationship. The data suggest that these ceramic films are more suitable than plain LOPE film for packaging fresh produce of high respiration rate.
