It makes sense that Lay’s would go by different names in different countries. After all, Lay’s doesn’t translate very well into other languages, nor should it. But to help sell the product in foreign markets, Frito-Lay had to be creative in marketing their chips to make them sound more palatable to consumers.
In Latin America, Lay’s doesn’t go by the name Lay’s. Instead, they’ve adopted the name Sabritas, which doesn’t actually mean anything. It’s the brand in Mexico that manufacturers the chips we all know and love (less than Pringles, of course). Papa Sabritas also makes Cheetos, Doritos, and Ruffles in Mexico and distributes them across South America.
