A few months ago we revamped our food storage containers, going from plastic to glass. We had talked about it before, and when we noticed Costco had a set with 10 containers for a reasonable price we went for it. I don’t recommend microwaving plastic containers, and with roommates, it would happen. I’ve also seen deteriorated plastic containers come out of dishwashers. I’ve seen oils leaching into the plastic (while plastic is most likely leaching into your food). At work I would transfer my food out of the plastic to another dish to heat it, which isn’t that much of a hassle, but now that I have Glasslock containers, I don’t need to do that anymore.
