Our 80th Anniversary: How we got here

Canadian Plastics

Canadian Plastics magazine turns 80 this summer, and what a long, strange trip it’s been. Here’s a look at our industry from World War II to COVID-19, and all the years in between, as we covered it.

Nineteen forty-three was a tumultuous year: World War II was in its fourth year, and factories throughout the West worked around the clock to supply goods for the war effort. There was a tremendous shortage of metal, wood, ceramics, natural fibres and rubber, and as a result, plastics begins to come into its own as a substitute material, as engineers and designers turned to phenolics and other plastic materials to produce hundreds of new products for both the civilian population and the military. And this, in turn, prompts the creation of Canadian Plastics magazine, with its first issue in August 1943. (It then went on hiatus until after the war due to a severe paper shortage, and resumed regular production in 1946.)

No single event had a greater impact on the plastics industry than the war, and this was apparent even at the time. “Canadian use of plastic materials has grown steadily and today is making a valuable contribution to our war production program,” our first editorial said. “Significant, as a result of this, is the new attitude of Canadian industrial designers and engineers toward plastics, and inescapable is the fact that employment of this material is going to take place on a broad manufacturing scale.”

Plastic – from a word that originally meant “pliable and easily shaped” – predated World War II by decades, of course, with the first plastics mainly developed as substitutes for ivory. In 1862, Alexander Parkes introduced “Parkesine,” the world’s first-ever man-made plastic, at the London International Exhibition, marketed as an alternative to ivory and horn that Parks discovered while trying to develop a synthetic substitute for shellac for waterproofing. Following on that, the first synthetic polymer was invented in 1869 by John Wesley Hyatt, who was inspired by a New York firm’s offer of $10,000 for anyone who could provide a substitute for – again – ivory, for use in billiard balls. By treating cellulose, derived from cotton fibre, with camphor, Hyatt discovered a plastic that could be crafted into a variety of shapes and made to imitate a natural substance like ivory, and also tortoiseshell, horn, and linen. In 1872, Hyatt and his brother patented the world’s first injection molding machine.


Fast forward to 1907 and Leo Baekeland invented Bakelite, the first fully synthetic plastic, meaning it contained no molecules found in nature. Marketed as “the material of a thousand uses,” Bakelite could be shaped or molded into almost anything, providing endless possibilities. International developments came regularly after that – in the UK, Rolls Royce started using phenol formaldehyde in its car interiors in 1916, Scotch tape was introduced in the U.S. in 1930, the first twin-screw extruder machine was introduced in Italy in 1936, the first commercial production of polystyrene (PS) began in Germany in 1937. And the industry was also building in Canada: William Zeidler of Toronto was the first Canadian to receive a patent for plastics processing for a method of polishing cellulose nitrate, in 1885; Granby Manufacturing Co., of Granby Que., starting making cellulose nitrate in 1908; Electroplax Ltd., of Toronto, began custom molding phenolic products in 1923; Canadian General Electric Co., of Peterborough, Ont., formed a plastics molding department in 1929; and French Ivory Products, of Toronto, installed the first injection molding machine in North America in 1930.

During World War II, plastic production in Canada and the U.S. increased by 250 and 300 per cent respectively. Nylon, invented by Wallace Carothers in 1935 as a synthetic silk, was used during the war for parachutes, ropes, body armor, helmet liners, and more. Plexiglas provided an alternative to glass for aircraft windows. The surge in plastic production continued after the war ended in 1945; exploded beginning in the 1950s; and became part of the zeitgeist in the 1960s, a moment that was cemented in the 1969 film The Graduate, with its confident prediction that “the future is one word: plastics.”

And as evidenced in thousands of cutting-edge applications in every product sector since then, plastics did indeed become – and still is – the future.
