Lay's Stax is a potato chip snack food produced by Frito-Lay, a subsidiary of PepsiCo.

[1] It was introduced in 2003 as direct competition for Procter & Gamble's (later Kellogg's in 2012 and Kellanova in 2023) Pringles.

[3] In the UK, Stax (under the Walkers brand) are packed in all-cardboard cans.

Since late 2006, Lay's Stax have been available in Brazil under the name "Elma Chips Stax", deriving their name from that of a Brazilian division of the PepsiCo corporation known as Elma Chips.

However, the yellow lids atop the cans are marked with the Lay's Stax brand name typical in most other regions of the world.
