Described herein are sealable, breathable bags for packaging, storing, and transporting fresh fruit in boxes. The bags protects the fruit from outside contaminants while maintaining a modified atmosphere environment around the fruit to preserve the freshness of the fruit. Furthermore, the bags are constructed in such a way that they have a flattened closed configuration and a fully opened configuration that allows them to efficiently fit into a generally cuboid, open-topped packaging box to be filled with fresh fruit and then seal around the fruit in the box. In one variation, the bag has a substantially trapezoidal shape with a wider mouth, or top opening, and shorter lower edge. |

1. A sealable bag for packaging fresh fruit within an open-topped box, the bag comprising:
a front outer panel, a front inner panel, a rear inner panel, and a rear outer panel formed from a folded sheet of polymeric material; wherein the bag has a flattened, closed configuration wherein:
the front outer panel transitions to the front inner panel along a first lower fold, the front inner panel transitions to the rear inner panel along an intermediate fold at upper ends of the front and rear inner panels, and the rear inner panel transitions to the rear outer panel along a second lower fold, such that the folded sheet forms a generally “W” shaped cross-sectional profile;the front outer panel, the front inner panel, the rear inner panel, the rear outer panel, the first and second lower folds, and the intermediate fold extend laterally along a length of the bag between a first sealed side of the bag and an opposing second sealed side of the bag;the first sealed side of the bag includes a first lower sealed side and a first upper sealed side, and the second sealed side of the bag includes a second lower sealed side and a second lower sealed side;the first lower sealed side comprises a joining of first lateral edges of the front outer panel, the front inner panel, the rear inner panel, and the rear outer panel below the intermediate fold, and the second lower sealed side comprises a joining of opposing second lateral edges of the front outer panel, the front inner panel, the rear inner panel, and the rear outer panel below the intermediate fold;the first upper sealed side comprises a joining of the first lateral edges of the front outer panel and the rear outer panel above the intermediate fold, and the second upper sealed side comprises a joining of the second lateral edges of the front outer panel and the rear outer panel above the intermediate fold;the front outer panel and the rear outer panel form an upper opening between the first upper sealed side and the second upper sealed side, and the front outer panel and the rear outer panel include an upper closure adjacent the upper opening, the upper closure configured to selectively seal closed the upper opening with fresh fruit packaged within the bag such that a modified atmosphere environment is created around the fresh fruit within the sealed bag; wherein the bag has a fully open configuration when the bag is placed in the open-topped box, the box having a rectangular lower panel, two rectangular end panels extending upward from opposing ends of the lower panel, and two rectangular side panels extending upward from opposing sides of the lower panel and extending between the two end panels; wherein in the fully open configuration, the bag overlies an upper surface of the lower panel and inner surfaces of the two end panels and two side panels of the box, and the upper opening of the bag is spread apart with upper edges of the front and rear outer panels being positioned adjacent to or folded over upper edges of the two side panels and the two end panels of the box, such that fresh fruit can be placed inside the bag within the box; and wherein the first and second sealed sides converge in a direction away from the upper opening to give the bag a substantially trapezoidal configuration. |
