Smurfit Westrock Plc

A maker of corrugated boxes, folding cartons, and other paper-based packaging used by food and consumer-goods companies around the world, formed in July 2024 when Irish box-maker Smurfit Kappa merged with American rival WestRock. Its roots trace back to a small Dublin cardboard-box business Jefferson Smurfit bought in 1938, which grew into one of the world's largest packaging empires. The name simply stitches together the two merged companies' names.
