A method of manufacturing a container for containing an oxygen sensitive products
from a heated plastic by blow molding the plastic with a compressed gas that is
inert to the oxygen sensitive product. The heated plastic may contain an oxygen
barrier layer or an oxygen scavenging component. The gas is also inert to the oxygen
scavenging component, if it is present. An exemplary compressed gas is nitrogen
gas. The blow molding may be extrusion blow molding, injection blow molding or
stretch blow molding. The plastic may be, for example, a polyolefin, a nylon, or
a polyester.
