Printpack’s Rampart Packaging Div. (Williamsburg, VA) and Winpak Portion Packaging (Langhorne, PA) thermoform the cups, which are bright red for Pringles’ original flavor and green for a sour cream and onion variety. Cups provide barrier from oxygen ingress, helping to extend shelf life, which is conservatively estimated to be at least eight months. Lidstock is supplied by Spiralkote (Orlando, FL), a div. of Fleming Packaging. The lamination includes .0015 aluminum foil and an ethylene vinyl acetate blend as a sealant layer. The material is printed flexographically in seven colors with a varnish overcoat to protect the inks.
