Tldr you just pop them out into a glass container and follow instructions as normal. Put a towel over the top if it needs to be covered.

My understanding is that polypropylene is the most stable plastic (with hdpe coming in at a close second) unless subjected to uv radiation. Of course, it depends on the co-polymer which is almost impossible to find on a product.
Hdpe is not supposed to have an issue with UV radiation however.
I wonder if the radiation that is emitted from a microwave has similar effects as UV radiation.
Short answer: no. It’s an entirely different wavelength and has other effects. UV does its damage by ionizing, which microwaves are fundamentally incapable of.
So the taken effect is a different one.
