1. A vessel comprising:
a thermoplastic wall having an interior surface enclosing a lumen;
a tie coating comprising SiOxCy or SiNxCy wherein x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3, the tie coating having an interior surface facing the lumen and an outer surface facing the wall interior surface;
a barrier coating having an interior surface facing the lumen and an outer surface facing the interior surface of the tie coating, the barrier coating being effective to reduce the ingress of atmospheric gas into the lumen compared to a vessel without the barrier coating; and
a pH protective coating comprising SiOxCy or SiNxCy wherein x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3, the pH protective coating having an interior surface facing the lumen and an outer surface facing the interior surface of the barrier coating, the passivation or pH protective coating being effective to decrease the dissolution rate of the barrier coating in the presence of a fluid composition having a pH between 5 and 9 in the lumen.
