When I was growing up in rural South Carolina upcountry, we often exchanged produce and foodstuffs with friends and neighbors. We used paper grocery bags, cotton cloth bags, glass jars, bowls, pots/pans, etc. Everyone saved the containers and either returned them to the original owner or passed them on with foodstuffs to the next person. I'm concerned about reusing plastics with foodstuffs because of possible leaching and contamination. Whereas many plastic manufacturers have stopped using BPA, they have gone to BPC which is as bad or worse. If you've ever put spaghetti sauce in a plastic container and seen the red staining, then do not be naive and think the interchange of materials is only one way.
