The effects of packaging treatments with either low density polyethylene (LDPE) or polypropylene (PP) films on the quality of leaf lettuce were evaluated. It was also stored within a plastic bag (LDPE and PP films) with 4 pelf orated holes (6mm diameter). Changes in weight loss, color difference, anthocyanin, chlorophyll, water content, and general appearance (shape of lettuce) ware investigated Total weight of leaf lettuce packaged within non-pelf orated films decreased slowly over the storage periods at 5 and $20^{circ}C$. The weight loss of leaf lettuce showed no significant difference between non-pelf orated and perforated films at $20^{circ}C$. General appearance in leaf lettuce stored at $20^{circ}C$ was not significantly affected by packaging treatments with LDPE and PP films. The shelf life of non-packaged leaf lettuce at $5^{circ}C$ was 8 days, whereas packaging treatments with LDPE and PP films showed freshness in leaf lettuce for 30 days of storage. Total chlorophyll and water contents of leaf lettuce packaged within pelf orated and non-pelf orated films decreased gradually during storage. However, no remarkable changes in color difference, levels of chlorophyll and anthocyanin, and water contents were observed in leaf lettuce packaged within perforated and non-pelf orated films. In this experiment, leaf lettuce packaged within LDPE or PP films without any punching holes at $5^{circ}C$ was the most desirable for extending the quality. These results suggest that non-pelf orated packaging treatment in combination with low storage temperature could be effective in prolonging the shelf life of leaf lettuce
