CA 2453694

A package for storing and shipping food products incorporates a multilayer film lid that includes a gas-impermeable exterior layer and a gas-permeable interior layer. The multilayer film lid is heat sealed to a flange of a tray upon which the food product is supported. The gas-impermeable layer may be delaminated from the gas-permeable layer when it is desired to expose the food to atmospheric gases. Separation of the gas-impermeable layer from the gas-permeable layer is facilitated by a film fracture feature included in the heat seal pattern adjacent a pull tab of the lid. The film fracture feature concentrates the separation forces exerted on the tab in a small area so that the gas-permeable layer of the lid readily breaks at the film fracture feature.
