3M's FC-807 treatment on the inside of the box keeps grease and liquids from seeping through. Smurfit-Stone Container (Chicago, IL) converts the winning box.
This box replaces a carton made from E-flute corrugated that included a separate insert made of 33#-test B-flute corrugated. 3M's FC-807 treatment eliminated this insert, so Dallas-based Pizza Hut reduced paper usage by about 6깪 tons annually. For economy, a plastic lid support was also eliminated because the new carton is made from stronger B-flute.
Another winner was a Krispy Kreme donut package that uses Scotchban protector FC-845 to extend shelf life. RockTenn (Norcross, GA) is the converter of the winning package. And a notable finalist in the awards program was the McWaffle Sticks carton for Oak Brook, IL-based McDonald's Corp. Supplied by Westvaco (New York, NY), the carton is treated with Scotchban protectors FC-807 and FC-807A to keep syrup from staining the paperboard and to preserve product crispness.
