Abstract
A container providing controlled atmospheric storage of fresh fruits and vegetables to improve retention of product freshness by adjusting the carbon dioxide to oxygen ratio, for the storage of said fruits or vegetable can be attained and maintained, thereby retarding premature maturation and spoilage. The environment is controlled by providing a microporous membrane panel of limited carbon dioxide and oxygen permeability on an otherwise substantially impermeable container. The size of this area is a function of its permeability, the amount and respiration rate of the contents, and the ratio of carbon dioxide to oxygen desired.
