Freezing in Plastic

I'm a big proponent of freezing food, and also a big proponent of re-using containers, whatever they may be. However, did you know that when plastic freezes, it becomes brittle? This also goes for plastic bags (such as the ones with zip tops), to some degree.

This becomes a problem when you, say, drop something frozen on the floor (or against other frozen items). You have the hard floor meeting something frozen solid (and ice crystals can be SHARP!), with brittle plastic in between. Even pin-holes, which are almost undetectable, will let air in and moisture out, leading to frostbite if you put it back in the freezer. If you drop it while removing from the freezer, you'll want to take care in the way you thaw it because it could leak.

I was reminded of this while I was thawing frozen tomatoes to use in spicy tomato juice, salsa, and tomato sauce. I put the bags of tomatoes in the bath tub to thaw since I could spread them out and there would be no danger of condensation damaging the surface underneath. I picked one up, and water just *streamed* out of a hole the diameter of my pinky finger. I was pretty thankful it was still over the bath tub!

I have experienced this on occasion but never more than when I was thawing a couple of bags of breastmilk about a year ago and opened my fridge to find it everywhere. All that "liquid gold" just down the drain. Now I'm very careful to put anything I'm thawing into a bowl/pan first. Learned my lesson the hard way.
