Effective March 23, 2000, BP Amoco Chemicals has obtained proprietary FDA clearance for the use of its NDC monomer in PET/N copolymers and PEN homopolymer intended for food and beverage packaging. This opens the market for using these high clarity, gas impermeable, thermally stable polymers for packaging all food types under all conditions of use. Two clearances allow blending of naphthalate in PET (polyethylene terephthalate) at any composition from zero to 100 percent. Under the terms of the clearances, granted exclusively to polymers made with BP Amoco's NDC (dimethyl-2,6-naphthalene dicarboxylate), NDA (2,6-naphthalene dicarboxylic acid) or both, the company may extend the privilege for use to resin producers and their customers. PET/N and PEN (polyethylene naphthalate) offer food and beverage manufacturers a long-awaited alternative to glass. "For industries trying to reduce shipping weight and breakage without sacrificing shelf life, PET/N and PEN provide the answer," says Uduak Udofia, BP Amoco's Director of Marketing and Sales for Packaging/Film. "The beer industry in particular is ready for a lightweight, shatter resistant bottle that is gas impermeable and able to withstand the high temperatures of tunnel pasteurization."
