A dual ovenable frozen and chilled ready meal tray – which it is claimed will stay cool to the touch from the freezer to the point it is removed from the oven – is now available in the UK. The makers say it can withstand temperatures from -40 deg C to +220 deg C and will not shatter when frozen or transported.

Manufactured by Danish company Hartmann, the dualpack ovenware tray is claimed to have significantly less environmental impact than similar CPET containers, in terms especially of recyclability, and carries ISO 9001 and ISO 14001 certification.

Made from moulded fibre pulp with a thin PET inner coating, it has even flanges and no corner creases for easier sealing, and special ovensafe properties that allow it to retain its rigidity and strength during cooking. The tray can be board lidded or heat-sealed.
