OF all the true household names, Tupperware must be one of the best known. As they say, it is amazing what you can do with plastic. That was the way Earl Tupper saw things back in the 1940s when he introduced his flexible plastic products to the American consumer. And the direct selling party sales system was created. More than 50 years on, and many international awards later, Tupperware storage products are found stacked neatly into kitchen cupboards everywhere. They have even earned a place in the Museum of Modern Art in New York as part of its permanent collection. The product has been in Hongkong for 20 years. Times have changed for this prestigious plastics line and at the Ideal Home Expo, a syndicated modern Tupperware kitchen will show just how the name has kept up with progress which has challenged it with super-efficient deep freezers and the microwave oven. As well, at the expo booth, there will be a Tupperware dining area, cooking demonstrations and custom kitchen planning tips. One of the revolutionary lines which will be on display is the Tupperwave 2000 microwave cookware which is made of hi-tech material to allow it to be transferred from freezer to microwave to table. The heat-and cold-resistant plastic can survive temperatures of minus 30 to 180 degree celsius. The stackable design means space-saving, while a grid keeps food free of moisture and also helps drain fat. Tupperwave 2000 was awarded an internationally recognised seal of excellence with a ''G-Mark'' from Miti in Japan.
