National Can had out-grown the series of buildings at Meadowbank.
A major new development was the purchase of a modern building on five acres at 50 Duffy Avenue Thornleigh, N.S.W. for $1,100,000. An additional 50,000 square feet was to be added to the existing building on the site. New metal decorating equipment had been ordered which would double the capacity. It also heralded the advent of another important new development, National Can’s first U.V. (ultra-violet) curing oven, the very latest in lithographic technology.
On 15 August 1978 (foundation day) the new Thornleigh plant, National Can’s largest, was formally opened. Over two hundred customers, suppliers and staff, saw Councillor Don Evans open the plant, with the official party including Harry and Billie Tyrrell, Les and Shirley Whitcroft, Frank and Lorraine O’Halloran, Alan and Hazel Pitman and Geoff and Norma Stevens.
