Abstract
A package including a vessel wherein at least a portion of the vessel wall is made of a double wall material is disclosed. The double wall material comprises an interior polymer layer enclosed by an exterior polymer layer and one of the polymer layers is a layer made of cyclic olefin polymer (COP) resin. The package comprising the double wall, a CVD coating set on the wall, and a medicament comprising at least one protein, peptide, and/or DNA sequence is disclosed. Methods for processing a vessel, for example to provide lubricity or hydrophobicity, are also disclosed. The interior surface of the seated vessel can be processed via the vessel port by PECVD. Vessel barrier, lubricity and hydrophobic coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed.
