What makes this version unusual is that it sports a clear polyethylene window so shoppers can see the colors and textures of the ingredients inside. The pouch and window were jointly developed by Lipton and flexible packaging converter Vitex Packaging (Granby CT). The patented process produces the windows in the laminated roll stock so the pouch can be formed filled and sealed on horizontal pouch equipment reportedly from Klockner Bartelt (Sarasota FL). Lipton declined to discuss the package specifics. According to reports Vitex gravure-prints coated one-side paper and die-cuts it and laminates a PE film with adhesive all in-line. The skewed die-cut and film window help avoid jams as the web is being formed. What isn't obvious about the package is a second chamber that holds a foil barrier pouch of flavorings. It's separated by a paper membrane from the compartment that holds the product ingredients near the window. Thus far the product visibility is making the product disappear from many store shelves.
