Abstract: A process for packing, cooling and shipping fresh produce incorporates a standard corrugated paperboard, stackable container without utilizing any water resistant chemical compounds, together with a moisture-impervious plastic bag which is inserted into the paperboard container. The free ends of the plastic bag extend upwardly and above the top plane of the paperboard container as produce is packed and thereafter allows an opening for a preselected amount of free water to be applied over the fresh-packed produce. Thereafter, the top of the bag is tucked in providing a loose closure and the package is palletized and inserted into a cooling chamber having a relatively low humidity where the temperature of the produce is rapidly brought down to its storage and shipping temperature. By having the paperboard container avoid the presence of any high humidity environment, the basis weights of the paperboard components can be reduced.
