Microwaving plastic

[Bassmansam]

Gf was making a sandwich and i noticed she put the butter dish in the microwave for ten seconds. My first thougts were that it was dangerous to microwave plastics?

What does gd advise on such matters? Will i be ok?

Usually we have some country life butter but we ran out and she insists on having this butter dish!

Have been working with plastics my entire life in various roles throughout the industry. I can assure you that if the container is designed for food then the plastic is food grade. If you look at the msds sheets for food grade plastics you will find that they are tested to not allow chemical leakage including through different levels of microwaves/radiation or whilst just sitting.

If that was the case we would all be getting sick in the same fashion people got sick eating from the earliest forms of tin cans.

Thank you, that is reassuring.
