Abstract
A vessel has an interior surface facing a lumen. The interior surface includes a tie coating or layer, a barrier coating or layer, and a pH protective coating or layer. The tie coating or layer can comprise SiOxCy or SiNxCy, where x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3. The barrier coating or layer can comprise SiOx, wherein x is from 1.5 to 2.9. The barrier coating or layer reduces the ingress of atmospheric gas into the lumen. The pH protective coating or layer can comprise SiOxCy or SiNxCy, as well. In an embodiment, in the presence of a fluid composition contained in the lumen and having a pH between 5 and 9, the calculated shelf life of the package can be more than six months at a storage temperature of 4° C.
