摘要

This invention relates to novel package systems for refrigerated modified atmosphere packaging of fresh fruit, vegetables and cut flowers. More particularly, this invention relates to the design, construction, closure, sealing and use of gas-permeable corrugated paperboard package systems for prolonging the storage life of fresh fruits, vegetables and cut flowers under modified atmosphere in the headspaces of the closed package system. A corrugated gas permeable paperboard comprising: (a) a first layer of Kraft paper; (b) a layer of polymer having a gas permeability which permits gas to be transmitted through the polymeric film at prescribed levels; (c) a second layer of Kraft paper, said first and second layers of Kraft paper sandwiching the polymer between them; (d) a corrugated fluting; and (e) a third layer of Kraft paper affixed to the corrugated fluting.
