Abstract: A “freezer to microwave oven” package (10) which can be heated in a microwave without consumer intervention. The package includes at least one venting arrangement present in a seal, the venting arrangement including a water compatible coating (28) that provides a vent from the interior of the package to the exterior, upon exposure of the coating to a fluid water source. The fluid water source (e.g., liquid water or vapor) solubilizes, dissolves or otherwise renders ineffective the coating, forming a fluid path from interior of the package to the exterior of package, thus allowing escape of pressure from the package.
