Abstract
El presente invento se proporciona polimerización asistida con plasma y deposición de un revestimiento de superficie interna muy delgado en un envase plástico o metálico sin un aumento deseable en la temperatura superficial del envase para modificar las propiedades superficiales de la superficie plástica interna de un envase por reacción de la superficie con un gas reactivo que ha sido energizado para producir un plasma o la superficie es activada por un plasma de gas reactivo de manera que se haga receptora a otra reacción superficial. El método comprende ubicar el envase en un recinto cerrado, insertar elementos para alimentar un gas reactante dentro del envase, controlar selectivamente la presión dentro del recinto cerrado y dentro del envase, limpiar una superficie del envase a ser revestida in situ, pre-tratar la superficie a ser revestida para permitir que un revestimiento polimérico subsiguientemente depositado sobre la misma asegure la correcta adhesión entre el material de revestimiento y el material de envase, alimentar un gas reactante de constitución predeterminada y que tenga propiedades de barrera dentro del envase, generar un plasma con dicho gas reactante y depositar un revestimiento polimérico relativamente delgado sobre la superficie a ser revestida, y efectuar un tratamiento de post-polimerización sobre dicho revestimiento polimérico para eliminar monómeros residuales y otros extractables poliméricos in situ después de la deposición de dicho revestimiento polimérico.The present invention provides plasma assisted polymerization and deposition of a very thin inner surface coating on a plastic or metallic container without a desirable increase in the surface temperature of the container to modify the surface properties of the inner plastic surface of a container by reaction of the surface with a reactive gas that has been energized to produce a plasma or the surface is activated by a plasma of reactive gas so that it becomes receptive to another surface reaction. The method comprises locating the container in a closed chamber, inserting elements to feed a reactant gas into the container, selectively controlling the pressure within the closed chamber and within the container, cleaning a surface of the container to be coated in situ, pre-treating the surface to be coated to allow a polymeric coating subsequently deposited thereon to ensure proper adhesion between the coating material and the packaging material, feed a reactant gas of predetermined constitution and having barrier properties within the packaging, generate a plasma with said reactant gas and depositing a relatively thin polymeric coating on the surface to be coated, and effecting a post-polymerization treatment on said polymeric coating to remove residual monomers and other polymeric extractables in situ after the deposition of said polymeric coating.
