Plastic in the microwave?

Again and again there is uncertainty, if and when certain plastic in the microwave allowed. What possible damage to unsuitable plastic are to be feared, and how to recognize microwaveable dishes, you can read in detail in this article.

Problem warming

The microwave does not heat directly via heat rays. The way the microwave works is a bit different. Water in food or in everything in the microwave is stimulated to move and warms up. This does not only apply to food, but in principle to everything.

In this type of heating, no external temperature plays a role, but rather how strongly the respective substance reacts to the stimulating radiation and heats up.

Microwaveable plastic

Plastics that are suitable for the microwave do not heat themselves under the influence of microwave radiation. Only the food contained in them react to the heat radiation.

Microwaveable plastic dishes are usually labeled - either on the packaging when purchased, or directly on the floor via an embossed mark. For plastics that are not, that's problematic.

It is recommended to use a suitable microwave for use in the microwave. If in doubt, you can also test yourself.

Test for microwave compatibility

A short quick test can be done by placing the plastic utensils that you are not sure empty in the microwave, and this for a very short time (about 15 to 20 seconds, no longer) turns on. If the crockery feels warm afterwards, it is not suitable for microwaves.

Plastic packaging

You can trust the bowls of ready meals specifically designed for microwave heating. However, other plastic dishes that are not intended for use may melt or, under certain circumstances, give off toxic substances when warm.

Tips & Tricks

You have to be particularly careful with dishes made of melamine, as it is often used as camping dishes. Melamine-coated or made of melamine crockery can deliver harmful substances to the food contained therein at temperatures above 70° C.
