Constar International Inc. (NASDAQ:CNST), a leading producer of polyethylene terephthalate (PET) plastic containers, will exhibit a family of unbreakable, lightweight Starshield (R) bottles for wine at the Unified Wine & Grape Symposium in Sacramento, Calif., January 24-26. Constar will exhibit with Encore Glass Inc. at Encore`s booth # 900/902. In Starshield (R) bottles, the exceptional protection against oxidation that is required by wine is provided by Constar's Oxbar(R) active oxygen scavenger which, incorporated in the walls of the bottle, can enable a shelf life of a year or more. Helping wine producers satisfy the need for innovative packaging for moderately priced wines, Constar presently offers claret bottle designs in 187 ml, 375 ml, 750 ml, 1L and 1.5L sizes. The bottles are available in clear or deadleaf green. Finishes for aluminum ROPP and plastic threaded closures are offered, affording tool-free opening and re-closing. Development continues on finishes having other types of closures suitable for wine. Modern wine drinkers prefer packaging that lets them enjoy wine wherever they go, including venues where traditional glass bottles are not allowed. StarShield(R) wine bottles from Constar can be conveniently and safely used at sports arenas and golf courses, beaches and barbeques, poolside and marinas allowing for more wine-drinking occasions. Light weight and unbreakability make StarShield PET wine bottles ideal for multi-packs, so marketers can move more product per purchase occasion. StarShield(R) PET bottles for moderate-priced wines provide an economical alternative to glass by affording cost savings throughout manufacturing and distribution, including savings in freight, elimination of breakage, and the further savings from plastic closures.
