ABSTRACT OF THE DISCLOSURE An environmentally sealed packaging system for the storage and transport of vegetables which relies upon one or more plastic bags and which may be contained in suitable paperboard containers. The plastic bags are usually of a large size and have a substantial thickness in order to withstand the rigors of transport and storage. Nevertheless, they are flexible and foldable. When produce, and particularly vegetables such as lettuce, is stored in the plastic bags, the upper ends are sealed by engaging two opposed outer side walls and rolling the two outer side walls together to form an enlarged roll. The ends of the roll are then folded inwardly and secured to the top in order to seal the opposite transverse ends. The rolling of the bags effectively seals the two sides together and with the folding of the ends the interior of the bag is then sealed. A releasable tape is then secured to the folded-in ends and to the roll in order to thereby hold the bag in a closed condition. When it is desired to reopen the bags, it is only necessary to peel the tape from the plastic bags. Various modes of tape placement are disclosed.
