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 substituted cyclodextrin 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.
