Abstract
An article or vessel is described including a vessel surface and a coating set comprising at least one tie coating, at least one barrier coating, and at least one pH protective coating. For example, the coating set can comprise a tie coating, a barrier coating, a pH protective coating and a second barrier coating; and in the presence of a fluid composition, the fluid contacting surface is the barrier coating or layer. The respective coatings can be applied by PECVD of a polysiloxane precursor. Such vessels can have a coated interior portion containing a fluid with a pH of 4 to 8. The barrier coating prevents oxygen from penetrating into the thermoplastic vessel, and the tie coating and pH protective coating together protect the barrier layer from the contents of the vessel. The second barrier coating is comparable to glass surface if needed.
