A gas-flushed microwavable easy-to-open food package is provided which is resistant to impact under temperatures at or below freezing and which is comprised of a flexible lidding film having oxygen-barrier properties hermetically and peelably sealed to a food compartment formed from a polypropylene copolymer material. The lidding film is preferably comprised of oriented polyester, and the food product compartment further comprises a peelable oxygen, barrier film, preferably formed of ethylene vinyl acetate, PVDC and a peelable polyethylene layer.

The package is particularly advantageous in that it provides impact protection and maintains freshness for a food product that is shipped frozen and kept at refrigeration temperatures near point of sale, and can also be microwaved to serving temperatures without thermal distortion.
A freezable and microwavable easy-to-open food package capable of containing a rapidly perishable food product that is visually assessable to the consumer prior to opening said package comprising:
An easy-to-open food package for a combination proteinaceous and farinaceous food product capable of maintaining the freshness of the food product at low temperatures while also being capable of withstanding microwave heating sufficient to heat the food product without thermal distortion and capable of having said food product visually assessed by the consumer while in said package, comprising:
