The structure of the deal sees KP Snacks buying the Popchips brand in the UK and Europe but another company, Popchips Inc, will continue to operate separately in North America and other markets.
Mark Thorpe, chief executive of KP Snacks, said: 'Popchips is a fantastic addition… and we believe it significantly strengthens our proposition.'
The deal comes hot on the heels of KP's recent takeover of Tyrrells crisps.
