Methods for processing a vessel, for example to provide a gas barrier or lubricity, are disclosed. First and second PECVD or other vessel processing stations or devices and a vessel holder comprising a vessel port are provided. An opening of the vessel can be seated on the vessel port. The interior surface of the seated vessel can be processed via the vessel port by the first and second processing stations or devices. Vessel barrier, lubricity and hydrophobic coatings and coated vessels, for example syringes and medical sample collection tubes are disclosed. A vessel processing system and vessel inspection apparatus and methods are also disclosed.

A flexible material for a flexible container can include a first laminate and a second laminate joined to at least a portion of the first laminate by at least one seal. The first laminate can include a first gas barrier layer disposed between first and second sealable layers, wherein the first and second sealable layers define opposed exterior layers of the first laminate. The second laminate can include a third sealable layer defining an exterior layer of the second laminate, and a second gas barrier layer. The at least one seal joins a portion of the third sealable layer to at least a portion of the second sealable layer.

Preferred embodiments relate to methods and apparatus for making articles made of polyester, preferably virgin polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of recycled or post-consumer PET and one or more layers of a material with good gas-barrier characteristics, preferably silicon oxide. Preferably, the recycled PET layer comprises about 25% to about 50% of the entire material content. Preferably the articles take the form of preforms and the containers are blow-molded therefrom and the barrier layer is subsequently applied. The preferred barrier materials have a lower permeability to oxygen and carbon dioxide than PET. In addition, the neck of the preforms and bottles is at least partially in the crystalline state and the body is primarily in the amorphous or semi-crystalline state. This structure in a preform enables the preform to be easily blow molded by virtue of the amorphous material in the body, while being able to have dimensional stability in hot-fill applications.

The invention relates to a method for preparing a graphene oxide / white carbon black / rubber nanocomposite, which adopts a solution blending method or a mechanical blending method. In the graphene oxide / white carbon black / rubber nanocomposite prepared by the method provided by the invention, graphene and white carbon black are inserted with each other to effectively effective the aggregation of the two fillers, so as to obtain a highly-dispersed highly-stripped nano-sized composite. Not only the composite has high modulus and low rolling resistance, but also the wear resistance of a rubber material is greatly improved, and the modulus and tear resistance of the composite are further improved; in addition, due to the lamellar structure and good self-recovery capability of graphene oxide, the rubber material is also endued with good gas barrier performance and self-recovery capability, and the nanocomposite has the advantages that cannot be matched by any traditional filler. The method provided by the invention is simple and feasible, and suitable for industrial production, and has low cost, wide application range and good economic and social benefits.
