The bag is aimed at convenience retailers and looks to capitalise on the increasing popularity of sharing bags and products with round price points, Nestlé said.
The launch follows the recent introduction of a £1 block for Aero.
The Aero Bubbles £1 bag will be available in both peppermint and milk varieties.
Nestlé said IRI figures showed the sharing bag market to be worth £758 million, up 8% by value in the year to July 17.
The company has also produced 35p price-marked individual packs of Rowntree’s Fruit Pastilles, Randoms, Smarties, Milkybar and Milkybar Buttons.
