Disposable foil packaging

The foil from which these containers are made has a unique alloy. The proportion of iron is 0%, which makes the use of the form in the microwave oven safe for both food and electrical appliances. Rules for using a foil mold in a microwave oven:
- remove the cover before use, do not cover the form,
- not to use damaged, cut forms,
- not to put a blank form in the microwave,
- to heat in one form,
- not to be used in microwave ovens manufactured earlier in 1981.
