Although I have problems with the environmental concerns about plastics in general (and how all plastics bring us to more oil use), as someone that has severe arthritis in the hands, "Zip-Lock" bags are helpful I mean the real "zip-lock" kinds. I wash and re-use them and usually put things in a container in the fridge that can be washed, but sometimes these just work the best.
Always a dilemma with some of these things!!
History
Ziploc brand zipper storage bags were introduced by Dow Chemical Company. According to Dow's website, the first Ziploc bags were test-marketed in 1968. This was the first time that the resealable bag was marketed as a way to keep food fresh. However, in 1954, a company called Minigrip, purchased the license to manufacture a resealable zipper bag. According to Minigrip's website, it manufactured the "first integral zipper plastic bag in the United States" in 1959. It wasn't until 1968 when the technology was licensed by Dow Chemical Company to be used for food storage.
