A small sampling of new product introductions by Canadian companies and inventors
The first plastic cups for coffee and hot drinks came on the scene in the late ’50s. A report from Canadian Plastics states that Polychemical Industries of Edmonton, AB, was possibly the first company to use expandable polystyrene for the production of hot drink cups. These foamed cups were called Thermokups. The first injection molded coffee cups followed about two years later, in 1959, made by Impac Containers (Toronto), according to Tom Thomas, then CEO of Canada Cup Ltd. The advent of injection molded cups combined with the popularity of coffee vending machines created a fast growing industry segment.
