When I worked at a school years ago, I asked the cooks to save for me any plastic bags they were going to toss (like bread & bun packaging). They were happy to oblige. Then a teacher asked what was going on, so I told her & SHE began saving HER bread wrappers from the store. I have an on-going supply & never have to buy bags. Anything I'm going to freeze, I stick in a used wrapper before putting it in a store-bought freezer bag. I have been using the same box of freezer bags for over 20 years.
