The old Plastalon building - built in the 1950s - in Dixon St was demolished on the weekend.
According to information published in the Wairarapa Times-Age in 1957, the building was opened on August 12 that year by Wairarapa Member of Parliament B V Cooksley.
The article reads: "Fine products demand efficient distribution, and the fast, all-weather freightway through the hills to New Zealand's most strategic point has thrown the door to the Wairarapa wide open.
"Quick to realise this were the promoters of Plastalon (NZ) Ltd, whose modern factory in Masterton is being opened this afternoon by the member for the Wairarapa.
"The interest shown in the Wairarapa by this combination of New Zealand and Australian resources is sound business, because the organisers can see what lies ahead."
