In an official statement, the American-owned business, estimated to be worth more than £400 million, explained that the plastic parts are shaped and sized like crisps, making them more dangerous.
The UK Food Standards Agency said; 'This means these products are a possible risk to health.'
The easiest way to tell if your crisps could be affected is to check the best before date, as all of the botched bags have a best before of 28th May 2016.
The affected products include the 150g bags of lightly salted crisps, which are sourced exclusively from Asda supermarkets, so if you've been shopping elsewhere for the 150g bags then you shouldn't be affected by the problem.
Other bags affected are the 40g bags of sea salt and balsamic vinegar, and mature cheddar and red onion, which could have been purchased from any retailer.
Extra care should be taken in regard to the smaller 30g bags of lightly salted crisps because they are often used as complimentary snacks or on train buffet cars, so people will not be aware of their original origin.
The company, which started UK production in Norwich in 1989, said; 'As a precautionary measure, we are asking customers not to eat the product and to contact us for a full refund.'
'If you have any of the products referred to in this notice please return the empty pack for a full refund including postage, together with your name and address to Kettle Foods Ltd, Barnard Road, Norwich NR5 9JP.
'We apologise for any inconvenience caused and thank our customers in advance for their cooperation.'
Kettle Chips was founded in Oregon, USA, in 1978 and was bought by San Francisco-based Diamond Foods. The brand specialises in gourmet crisps, nuts and tortilla chips.
