Abstract
A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform.

A preform for forming a finished container, the preform comprising:
- a top section having only one layer;
- and
- a bottom section comprising an outer layer, an intermediate layer and an inner layer, the intermediate layer comprising an additive.
A preform for forming a finished container, the preform comprising:
- a top section having only one layer consisting of polyethylene terephythalate, the top section comprising a threaded neck;
- and
- a bottom section comprising an outer layer, an intermediate layer and an inner layer, the outer layer and the inner layer each consisting of polyethylene terephythalate, the intermediate layer consisting of polyethylene terephythalate and an oxygen scavenger,
- wherein the inner layer and the outer layer each have a first thickness, the intermediate layer having a second thickness that is less than the first thickness, and
- wherein the oxygen scavenger is present in the finished container in an amount between 0.1 wt. % and 5.0 wt. % of the finished container.
