Skips and Nik Naks are ­being relaunched in a bid to ­revive declining sales.

The brands are being given new pack designs that includes a range of 46p price-marked handy packs and a flash to highlight the 82-calories content of Skips. United Biscuits is also changing the flavour line-ups.

The company said social network campaigns had prompted it to reintroduce Scampi’n’Lemon flavoured Nik Naks to six-packs (rsp: £2.09), where they will replace Pickled Onion, and Sizzling Salt & Vinegar is ­being added to six-packs of Skips (rsp: £2.05).

“Consumers have been campaigning passionately for new flavours and we’re delighted to be able to respond to this,” said UBUK bagged snacks marketing director George Johnston.

Sales of Skips have fallen 17% year-on-year to £20m, while Nik Naks have slumped 18% to £11m over the same period [Nielsen 52w/e 13 August 2011].
