Fruits, veggies: Killer app for clear plastic cans?

摘要

Premium-grade vegetables, chunked fruit, and jellied cranberry sauce are likely to be among the first foods to be commercially packed and marketed in clear barrier plastic cans. Several retortable plastic food can technologies are in the final stages of development. At least two of them-the TruVue™ extrusion-molded can from Sonoco Products Co. and a rotary thermoformed straight-walled plastic can made by Silgan Plastics of a clarified polypropylene/EVOH structure-will likely be exhibited at PACK EXPO International in Chicago in November. Even before then, one of Sonoco's customers is expected to put a clear barrier plastic food can on supermarket shelves in the Southeast.
