Frito-Lay has introduced new 100% compostable packaging for its popular Sun Chips snacks made from plant-based materials, with the help of Memphis-based packaging firm Bryce Corp. This is a breakthrough in more sustainable food packaging that can protect the product and then be renewed by nature. While previously only one-third of Sun Chips bags used renewable materials, now the same size bags are fully compostable. If successful, Frito-Lay aims to extend this packaging to all sizes of Sun Chips by the end of 2010.
