The Jif plastic containers were originally made from polythene, and were one of the original and first blow moulded containers used for food applications. The plastic containers served to replace glass bottles used to package lemon juice. The plastic container was the brainchild of Edward Hack, and the container's design was undertaken by Bill Pugh, the chief plastics designer at Cascelloid. In its development, Pugh carved a core made of wood, covered it with fresh lemon peel to give it a realistic texture, and then cast a plaster mould. This led to the realistic-looking container that significantly resembles a lemon. Some sources have stated that similar plastic lemon packaging existed in Italy at the time of the end of World War II, prior to the time of the packaging design in the United Kingdom. History Hax, Realemon and ReaLem brands Edward Hack developed the original idea and model of lemon juice being contained inside lemon-shaped and coloured packaging in the 1950s. The product was then designed and produced by Cascelloid Ltd. Hack presented Cascelloid with a fresh lemon he acquired at Covent Garden, upon which to base the plastic container. Hack had performed significant searches at several markets to find an optimal model. Cascelloid stated that Hack reviewed and evaluated the entire inventory of lemons at Fortnum and Mason's, Selfridges, Harrods and Covent Garden, the latter of which involved examining three cases of lemons that contained around 300 lemons in each case. Stanley Wagner had been brought up in the wholesale fruit business, his father having a very substantial company in Spitalfields Market. Bill Pugh, the chief plastics designer at Cascelloid, based in Leicester, and former Royal Air Force pilot, created a prototype of the blown lemon-shaped plastic shaped container based upon Hack's idea sometime in the 1950s, as well as other types of blown containers. Pugh's experimented with the initial design until he was satisfied with its appearance. This plastic lemon product was then used for Hax lemon juice. Edward Hack, Ltd. produced and marketed Hax brand squeezable plastic lemon containers filled with two ounces of Sicilian lemon juice. Per Edward Hack, Ltd., the juice was unfiltered, had no water added to it, and contained a preservative to prevent spoilage. Retailers could purchase the product in packs of six bags that contained 12 squeeze packs each, totalling 72 units. Upon introduction to the marketplace, Hax juice and the plastic
