For the refrigerator, we have a number of glass containers (Pyrex) with glass or plastic lids. For the freezer, we use plastic containers with plastic lids. We use very little plastic wrap. I take my sandwich and fruit to work every day in reusable plastic containers which we have had for over ten years.

I've slowly been switching over to glass containers (replacing Tupperware-type containers) because I don't want to reheat food in plastic. I tend to use plastic wrap more than plastic bags, but I have major guilt every time I toss one into the trash.
