A package for the storage of food or other suitable products includes a tray and, optionally, a lidding film. The tray is thermoformed, molded, or otherwise shaped to provide a recessed portion and flange, the recessed portion defining a product-receiving cavity. The flange includes a frame portion surrounding the cavity and a margin portion disposed alongside the frame portion and, in some embodiments, extending substantially a full width of the tray. The optional lidding film attaches to both the frame and margin portions and typically seals the cavity. The margin portion and a side wall of the recessed portion may include locking features to allow the margin portion to snap close against the side wall. The package may then be made to stand on end with the margin portion acting as a base. The lidding film may include a peelable/sealable film to allow repeated access to the product while sealing the cavity between uses.

Snap close peel reseal package

An end-sealed packaging bag comprising a multilayer non-heat shrinkable film and an easy open lap seal is provided. The film comprises at least four layers, including an inner heat sealing layer, a contaminated layer, a barrier layer, and an outer heat sealing layer. The film, when formed into a bag, is defined by a front panel, and opposing back panel connected to one another by a pair of side gusset panels. The bag further comprises a peelable lap seal connecting the inner heat sealing layer to the outer heat sealing layer of the film. The bag further comprises a first end seal connecting the inner heat sealing layer on the front panel with the inner heat sealing layer on the back panel between the side gusset panels and proximate to the first end of the bag.

Gusseted bag with easy-open lap seal

A rigid or semi-rigid tray is provided, including a bottom and at least one side wall which forms at least one recessed product-receiving compartment, and a flange extending around the tray which forms distal edges of the container. The tray further includes a lidding film affixed to the flange which forms a peelable heat-seal extending around the product-receiving compartment and the distal edges of the container, and an easy-open member positioned between the product-receiving compartment and the distal edges of the container. The easy-open member has a frangible portion of the lidding film which forms a tab member when punctured, for example by the force of a human finger, to provide a means for removing the lidding film from the flange and gaining access to the product-receiving compartment.
