Panasonic NN-3456 - Microwave Container Materials Guide; Approved and Restricted Materials

TIN FOIL
Small amounts of smooth tin foil can be used to
SHIELD joints of meat during defrosting and
cooking, as the microwaves cannot pass
through the foil, this prevents the parts shielded
from overcooking or overdefrosting. Take care
that the foil does not touch the sides or roof of
the oven, as this may cause arcing and damage
your oven.
ROASTING BAGS
Roasting bags are useful when slit up one side
to tent a joint for roasting by power and time. Do
not use the metal twists supplied.
PAPER
Plain white absorbent kitchen paper (kitchen
towel) can be used for covering blind pastry
cases and for covering bacon to prevent
splattering BUT FOR SHORT COOKING TIMES
ONLY. NEVER RE-USE A PIECE OF KITCHEN
TOWEL. ALWAYS USE A FRESH PIECE OF
PAPER FOR EACH DISH.
Avoid kitchen paper containing manmade fibres.
If you are using branded re-cycled kitchen
towel, check first that it is recommended for
microwave use.
Do not use waxed or plastic coated cups or
plates as the finish may melt in the oven.
Greaseproof paper can be used to line the base
of dishes and to cover fatty foods e.g. bacon
rashers to stop them splattering.
White paper plates can be used for SHORT RE¬
HEATING TIMES. .
CUNQ FILM
Microwave cling film can be used for covering
food that is reheated by microwave. It is also
useful for covering food to be cooked, but care
should be taken to avoid the film being in direct
contact with the food.
WICKER. WOOD, STRAW BASKETS
Do not use these items in your microwave. With
continued use and with prolonged exposure they
will crack and could ignite. Do not use wooden
dishes in your microwave.
PLASTIC
There are many plastic containa's designed for
microwave use.
Only use Tupperware® containers if they are
designed for microwave use.
Do not use Melamine - although it is heat
resistant it absorbs microwave energy and
scorches.
Even if a container is microwave safe, do not use
for cooking foods high in sugar or fat. Foods that
require long cooking times e.g. brown rice,
should not be cooked in plastic.
Never cook in cream or margarine cartons or
yoghurt pots, as these will melt with the heat from
the food.
Many plastics that are not heatproof for cooking
are suitable for defrosting.
