Aluminium foil and microwave ovens

Aluminium trays in the microwave oven: The right way to do it

The aluminium lid must be removed from the tray before use.
The meal should cover most of the floor of the tray.
Place the aluminium tray in the middle of the turntable in the microwave oven.
Attention if your microwave oven is equipped with a metal turntable, please place a ceramic or glass plate beneath to tray.
(Minimum distance to the walls: 2 cm)
The aluminium dish must not come into contact with the walls of the microwave oven.
Only one aluminium tray may be used in the microwave oven at a time.

The use of alufoil containers in microwave ovens is safe

Conclusive evidence that aluminium foil packaging can be used safely in microwave ovens has been established by a study from the Fraunhofer Institute for Process Engineering and Packaging IVV in Freising, Germany.

The results dispel the myth that aluminium foil containers are unsafe for use in microwave ovens and prove that consumer fears about using alufoil packs in the microwave are unfounded.

In fact in some instances consumer convenience is improved as not only are alufoil packs more rigid, something that is equally applicable to dual-ovenable containers, the use of aluminium foil enhances the appearance of the food when heated in the microwave oven. For example the study found that in the case of lasagne heated in a
microwave oven its visual appearance was superior as a brown crust was formed on the surface.

Conducted on behalf of the European Aluminium Foil Association (EAFA) with the support of the Aluminium Foil Container Manufacturers Association (AFCMA) the study concluded, “Microwave heating of food packaged in aluminium foil trays or in plastic containers with aluminium foil or aluminium laminated lids is perfectly viable.”

No hazardous results or damage to ovens were found in the more than 200 food portions that were heated in aluminium foil containers or packs containing aluminium foil.
