I believe Cellophane bags can also be used to store food in freezers, without leeching chemicals into the food. I have an organic hobby farm, and store fruit and vegetables in these bags for winter use.
COMMENT FROM DEBRA: My personal experience with cellophane bags is that they don't hold up very well to use or water. I would think they would break down fairly rapidly in the freezer, but have never tried this? Has anyone actually tried cellophane bags in the freezer?
