<p>A gas-flushed microwavable easy-to-open food package (10) is provided which is resistant to impact under temperatures at or below freezing and which is comprised of a flexible lidding film (12) having oxygen-barrier properties hermetically and peelably sealed to a food compartment (14) formed from a polypropylene copolymer material. The lidding film (12) is preferably comprised of oriented polyester, and the food product compartment (14) further comprises a peelable oxygen, barrier film (16), preferably formed of ethylene vinyl acetate, PDVC and a peelable polyethylene layer. The package (10) is designed to contain a perishable food product, such as a wiener in a bun or other proteinaceous-farinaceous food combinations, and is preferably entirely or partially transparent so as to allow the consumer to readily observe the condition of the food product before purchase. The package (10) 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. <IMAGE></p> |
