John has already covered the polylactic acid SunChips bags in several posts , so there’s little need for additional comments on the package, its properties, its benefits, or its shortcomings. As someone in the food industry , I have two observations. The first is that this is a very public launch and failure. Most packaging changes are barely noticed by the consumer and are set up to be seamless. For example, ConAgra launched a new 46 ounce ketchup bottle two years ago. The bottle won an industry award, but I don’t believe the launch was ever noted on the product.
The second observation is that SunChips will likely be a laboratory for green packaging for some time. Two years ago, SunChips packaging advertised a partnership with TerraCycle, a company that was (and is) looking for ways to recycle plastic and develop green technologies. I don’t recall seeing similar information on any of Frito-Lay’s other products, so a recycling outlook will likely be part of the brand’s identity.
