Abstract:
A dual-ovenable tray useful for supporting a food product. The tray comprises a sheet having first and second layers comprising one or more polyamides. The first layer of the sheet forms the tray inside surface. Where the first layer has a melting point, the second layer has a melting point of at least about 210° C. and at least 20° C. greater than the melting point of the first layer. Where the first layer has a glass transition temperature of less than about 120° C. measured at a 50% relative humidity, the second layer has a melting point of at least about 210° C.
