This study was conducted to investigate the effects of plastic film packaging with different film sources and thickness on the shelf life and market qualities of cucumber during the MA (modified atmosphere) storage. Among plastic film sources, the higher weight loss occurred in CE (ceramic film), LA (LDPE film+antifogging agent), LD (LDPE: low density polyethylene film) in the order. Also, the weight loss decreased along with the increase of thickness in the same plastic films. However the highest weight loss of CE 0.02 ㎜ film treatment was less than 1.3% during 12 days. CO₂ concentration in all film treatments increased gradually during the storage. Specially CE film was showed the lower CO₂ concentration than LD and LA film. C₂H4 concentration increased gradually during the storage, but it was not found in 0.02 ㎜ film in all kinds and 0.03 ㎜ CE film. Vitamin C content was reduced with the increase of storage period, but there were not found significant differences among film sources. Firmness gradually decreased during the storage and it was low in a 0.02 ㎜ film. In this results, CE 0.02 ㎜ film was the best for the keeping of shelf life of cucumber in this experiment.
