The British biscuit and snack manufacturer plans to exploit the strategic significance of the brands.
"Nik Naks and Wheat Crunchies are well loved consumer brands and I am delighted that we will be able to add them to the UK snack portfolio," said Benoit Testard, managing director of United Biscuits UK.
The brands will continue to be produced at Golden Wonder's factor in Scunthorpe under a co-manufacturing agreement with Tayto, which acquired the facility.
Tayto recently acquired Golden Wonder's two production facilities and all of its brands after the company went into administration.
Family-owned Tayto tabled a bid rumoured to be around £15m for Golden Wonder's production facilities and brands.
The deal built on Tayto's previous acquisition of the Pringles brand from Golden Wonder in January.
Golden Wonder cited the fiercely competitive UK crisps market for its downfall, which became inevitable after consecutive heavy losses for the company.
The company suffered losses of £10.8m on sales of £87.8m in 2004, and it is expected to reveal more losses for last year. The figures have not been released yet, but the administrators confirm they are "significant".
Conversely, United Biscuits had 2004 sales of £1.4bn, an increase of 4.6 per cent. The company owns some of the most well known snack brands in the UK, such as McVitie's and Jacob's.
