    Abstract: The present invention describes both a stretch-blow-molded opaque polyester container and a method of making it. The container, typically a beverage bottle has less than 15% transmission of visible light (500 nm) through a 0.4 millimeter wall thickness. It contains from about 0.1 to about 5wt. % of said opacifying material. The opacifying material may be any material compatible with polyester resin. The method of making the container includes introducing the opacifying material during polymerization, or prepared as a master batch for mixing with the polymer. Selection of certain opacifying materials can also result in favorable reheat properties, gas permeation-barrier improvements, and when the resin contains both opacifying material and oxygen scavenger there can be a synergistic effect with respect to CO 2 permeation.

    Abstract: Volatile organic compound or other materials are produced in the thermoplastic manufacture of thermoplastic polyester beverage containers. Such materials can be eluted into beverages such as carbonated beverages, sparkling or still water from the polyester. Such thermoplastic polyester resins can be manufactured with a material that can prevent the formation of, or react with, and absorb volatile by-products during the formation of thermoplastic preforms or containers from the thermoplastic pellet or chip. Further, as the preform is blown into a polyester container, the active materials of the invention prevent the generation of additional undesirable volatile materials. Lastly, the scavenger material can act as a barrier that prevents transport of materials from the exterior of the container into the container contents.

    Abstract translation: 在热塑性聚酯饮料容器的热塑性制造中生产挥发性有机化合物或其它材料。 这些材料可以从饮料中洗脱出来，例如碳酸饮料，来自聚酯的起泡或静止水。 这种热塑性聚酯树脂可以由在热塑性颗粒或芯片形成热塑性预制件或容器期间可以防止形成或反应并吸收挥发性副产物的材料制造。 此外，当预成型坯吹入聚酯容器中时，本发明的活性材料防止产生另外不期望的挥发性物质。 最后，清除剂材料可以作为防止材料从容器外部运输到容器内容物中的屏障。
