Baby products are often made from stuff which at least in theory should be less harmful, but I suppose it's only tested for a select group of hazards.
EDIT: forget the bamboo - not microwave safe. I ate some glue along with my dishes apparently.
EDIT2: Apparently wheat bran containers are microwave safe and since they're edible, they can't be lined with plastic. Not reusable of course.
Also I wouldn't put them on 100%, because low-water content stuff tends to burn in a microwave oven.
Different values or something else...
Hard problem to solve. I wonder what the best effort-per-payoff is in this scenario. Perhaps cutting out plastic water bottles would be 90% of the benefit, and the plastic containers for food is 10% of the benefit but tremendously more effort -- I don't know (never did research on this).
Beeswax food wraps work surprising well
PFAS coated paper?
