Winning Silver was the Tetra Wedge Aseptic Microwavable 200S stand-up pouch, a close cousin of the Tetra Wedge package that won the Diamond Award (see page 91) in this year’s DuPont competition. While the diamond award winner was notable for its transparency, this wedge impressed judges because it’s believed to be the first microwavable aseptic package. Once again, a plasma deposition of silicon oxide on PET film serves as the barrier material instead of the layer of foil traditionally used in conventional aseptic brick packs. Like the transparent package, this one is also formed and filled on a Tetra Pak (www.tetrapak.com) Model TBA-19 filler.
