Jiffy bag seems to be the name given to any kind of mailing envelope with a paper outer and some form of cushioning as a liner. The original Jiffy Bag was the Padded Envelope introduced by Jiffy in the 50s and still going strong. The Padded bag has a very strong pure Kraft paper outer and a lining of macerated paper fibres. The "Padded Bag" remains the only truly eco-friendly postal bag as it is easily reusable and recyclable.
