HEAT-RESISTANT EASY-OPEN PACKAGE

摘要

The present invention is directed to manually openable heat-resistant packages for containing a product that include a thermoformed tray having a product receiving area and a sealing flange endowed with sufficient heat resistance to withstand the cooking and/or pasteurization/sterilization conditions required to produce a ready-to-eat packaged meal. The tray comprises a bulk layer, and a heat sealing layer in direct contact with the bulk layer. The inventive packages also include a flexible transparent lidding film covering the thermoformed product receiving area comprising a heat sealing layer. The package includes a hermetic seal comprising a perimeter heat seal which circumvents the thermoformed tray formed by heat sealing a portion of the heat sealing layer of the lidding film to the sealing flange of the tray. Only the heat sealing layer of the tray is readily frangible and renders the heat seal manually peelable.
