When it comes to bagged salad, it’s usually a one-size-fits-all approach. However, for Ready Pac Foods, Inc., it’s all about diversity, functionality and sustainability. In fact, the Irwindale, Calif.-based refrigerated salad producer has been leading the way in sustainable packaging, product innovation and cutting-edge flavor profiles since 1969 when founder Dennis Gertmenian prepared his first customized on-the-go salad order.
