Abstract
A method, composition and system for coating an external surface of containers and in particular, plastic containers, provides for low permeability to gases and vapors. The coating applied to the external surface of the containers is very thin and is comprised of one or several inorganic substances or layers of substances. For example, the coating can include silica which is bonded to the external surface of the container. This coating will be flexible and can be applied regardless of the container's internal pressure or lack thereof. The coating will firmly adhere to the container and possess an enhanced gas barrier effect after pressurization even when the coating is scratched, fractured, flexed and/or stretched. Moreover, this gas barrier enhancement will be substantially unaffected by filling of the container.
