The July, 1940 edition of Popular Science heralded the miraculous appearance of a bold new means of packaging pickles: "Transparent rubber!"
Pickles, packaged in envelopes of a transparent rubber product, have been introduced by a leading American food packer. The water-tight container, which is protected by a cardboard box, holds neatly arranged sweet pickles which are packed in fluid just as when they are sold in glass bottles. Besides increasing the attractiveness of the commodity, the new method of packing is reported to eliminate bottle breakage and to reduce the weight of the containers.
