finish, a body portion and a base portion, the body portion
being stretched at a planar stretch ratio on the order of 9
to 12 to produce a moderately high degree of biaxial
orientation with orientation induced crystallinity, said
orientation providing both thermal stability and a high
resistance to internal pressurization of the container, the
base portion being substantially thicker than the body
portion to provide both thermal stability and a high
resistance to internal pressurization of the container;
filling the container with a hot product at a temperature on
the order of 185-190°F;
internally pressurizing the filled container at a
pressure on the order of 40 to 45 psig; and
applying a closure to the neck finish, wherein the
hot-filled pressurized container does not undergo any
substantial vacuum collapse or creep deformation.
