Abstract
A packaging device including a breathable or non-breathable, microwavable composite film structure in the form of a bag, a tray or other type of container is disclosed. The device may include atmospheric control attributes in the form of microperforations, and steam venting mechanisms in the form of precision cuts or channels. The microperforations may form atmospheric conditions within the device for the storage of perishable and/or respiring food products, and the steam venting mechanisms may regulate the pressure and/or heat within the device during microwave cooking of the food products within.
Claims20
A package for steam cooking food in a microwave, comprising:
- a multi-layer film structure which forms an enclosure in which the food is contained;
- a respiration system including one or more atmosphere control attributes (ACA) that are formed in the film structure, that extend all the way through the film structure from the enclosure to the environment outside the package, that are open prior to a microwave steam cooking operation, and that reduce the respiration of the food prior to the microwave cooking operation by allowing the transmission of gases between the enclosure and the environment outside the package through the one or more ACAs, thereby altering the atmosphere in the enclosure;
- and
- a steam venting system including a plurality of steam vents that are formed in the film structure, that remain closed prior to the microwave steam cooking operation by extending a depth that is less than entirely through a thickness of the film structure, and that open up to release pressure in the enclosure created during the microwave steam cooking process,
- wherein the film structure comprises at least one adhesive including one or more of the plurality of steam vents extending a depth that is less than entirely through a thickness of the at least one adhesive and at least one of the plurality of steam vents at least partially overlaps with at least one of the one or more atmosphere control attributes.

A package for steam cooking food in a microwave, comprising:
- a multi-layer film structure which forms an enclosure with an innermost layer adjacent to the food therein contained;
- a respiration system including one or more atmosphere control attributes (ACA) that are formed in the film structure, that extend all the way through the film structure from the enclosure to the environment outside the package, that are open prior to a microwave steam cooking operation, and that reduce the respiration of the food prior to the microwave cooking operation by allowing the transmission of gases between the enclosure and the environment outside the package through the one or more ACAs, thereby altering the atmosphere in the enclosure;
- and
- a steam venting system including a plurality of steam vents that are formed in the film structure, that remain closed prior to the microwave steam cooking operation by extending a depth that is less than entirely through a thickness of at least one layer of the film structure, and that open up to release pressure in the enclosure created during the microwave steam cooking process,
- wherein the film structure comprises at least one adhesive including one or more of the plurality of steam vents that extend a depth that is less than entirely through a thickness of the at least one adhesive and operationally couple upon the microwave steam cooking operation.

- and
- a steam venting system including a plurality of steam vents that are formed as precision cuts in the film structure, that remain visually closed prior to the microwave steam cooking operation by extending a depth that is less than entirely through a thickness of the film structure, and that open up to release pressure in the enclosure created during the microwave steam cooking process,
- wherein the film structure comprises at least one adhesive including one or more of the plurality of steam vents that extend a depth that is less than entirely through a thickness of the at least one adhesive and at least one laminate including one or more of the plurality of steam vents extending a depth that is less than entirely through a thickness of the at least one laminate,
- wherein at least one of the one or more of the steam vents in at least one of the adhesive and laminate at least partially overlaps with at least one of the one or more atmosphere control attributes.
