SportsOneSource媒体2007年11月1日报道：CamelBak（驼峰）将其所有的水壶生产线重新改进，产品将使用一种新的材料。CamelBak已与Eastman（伊士曼）公司合作，水壶/水袋将由伊士曼共聚酯制成。

　　该BPA-free材质的水壶将使用经典Classic Cap盖，并在明年2月初上市。预计到2008年春季，原采用CamelBak咬阀专利技术的Better Bottle系列产品将逐渐从聚碳酸酯材料过渡到使用伊士曼Tritan材料。新型的各色咬阀型Better Bottle水壶将在明年2月面市。

　　伊士曼共聚酯--独特的乙二醇改性的聚对苯二甲酸乙酯的开发，可用于粘合纤维及深染。产品的特性粘度在0.47～0.70之间。共聚酯可用于单组份和双组份的粘合纤维。

　　CamelBak is converting its entire line of re-useable water bottles to a new material that is 100% free of bisphenol-A (BPA). CamelBak has teamed with Eastman and the bottles will now be made from Eastman Tritan copolyester.

　　The BPA-free Better Bottle with Classic Cap, will ship in early Feb. The Better Bottle with the patented CamelBak Bite Valve will transition from polycarbonate to Tritan with a complete changeover expected in spring ‘08. New colors of the Better Bottle with Bite Valve, introduced in Feb, will all be made from BPA-free Eastman Tritan copolyester.
