ATLANTA - Carters Packaging of Nottingham, England, is looking for a customer to commercialize bottles made from polyethylene napthalate copolymer resin recently made available by Shell Chemical Co. Carters, a subsidiary of Hero Drinks Group UK Ltd., developed and tested the PEN resins in one-trip and returnable bottles. Shell announced April 20 in Atlanta that it is gearing up 20 million pounds of annual production for PEN and its precursor components at its Point Pleasant, W.Va., plant.
Bill Taylor, managing and sales director for Carters, said its tests showed that PEN can be processed on normal machinery, and is cost-competitive with glass, while offering the weight and impact advantages of plastic.
``We found that PEN was much better than PET, with which we have much experience, in hot-fill applications,'' Taylor said in a telephone interview.
``It has improved [ultraviolet light] barriers, and could be rewashed at 85§ C [185§ F], with no distortions,'' he said.
The tests also showed the bottles can be washed with 2 percent sodium hydroxide, without damage, and outperformed heat-set PET in either pre- or post-bottled pasteurization.
Carters developed the bottles to withstand the rigors of the European bottle return and recycling system.
