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 SiO x C y or SiN x C y , 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 SiO x , 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 SiO x C y or SiN x C y , 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. |
