Walkers and Birds Eye are set to raise the prices of some items due to the falling strength of the pound.
The pound has fallen 18% against the US dollar since June’s UK Brexit vote.
Walkers said that while its potatoes were British, it imported a number of different ingredients and materials to produce a finished packet of crisps.
These items include seasonings, oil for frying and key raw materials used in its packaging film.
