Brands involved in the makeover include Skips, Nik Naks, Wheat Crunchies and Discos. The packs for Skips, Nik Naks and Discos incorporate a brightly-coloured strip saying '50% less saturated fat, same great flavour' and feature a sunflower logo to indicate that the products are made with sunflower oil.
United Biscuits has added a number of variants to coincide with the relaunch: BBQ Beef Discos, a Worcester Sauce Wheat Crunchies multipack and Scampi & Lemon Nik Naks, also in multipack.
The bagged-snacks category is worth £1.9bn, according to ACNielsen.
