This study investigates the effect of two different types of packing films, OLAF and D1050, with different water vapor transmission rates, MAP with 15% carbon dioxide (CO2) and 85% nitrogen (N), variations in the number of micro perforations (11/18) in films, variations in weight (400 or 650 grams) and package size (1.5 or 2 lb.) to evaluate the effect on strawberry shelf life. All package combination were Compared to the typical clamshell packing with 650 grams of strawberry (control) to measure the effect of different variations on the shelf life of strawberries, and at the same time obtain new information that helps to optimize the engineering packing design.
