Abstract

Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by treating the article substrate by one or more methods selected from flame treatment, corona treatment, ionized air treatment, plasma air treatment and plasma arc treatment and dip, spray or flow coating. Additionally, a method comprises injection molding a first substrate material to form an article, treating the article surface by one or more methods selected from flame treatment, corona treatment, ionized air treatment, plasma air treatment and plasma arc treatment, and overmolding the article substrate with one or more barrier materials.

Description

Method of forming multilayer articles by surface treatment coating related application Under 35 U.S.C. § 119(e), this application claims provisional applications 60 / 726,973 filed October 14, 2005, 60 / 737,536 filed November 17, 2005, and 60 / 761,667, which are hereby incorporated by reference in their entirety. technical field The present invention relates to the surface treatment of articles, including articles having gas barrier and water resistant layers. It also relates to methods of making such surface treated articles by treating one or more surfaces of the article before, during and after forming one or more layers on a substrate of the article. Background technique A preform is a product used to make articles such as containers by blow molding. A large number of plastics and other materials have been used for containers and many are very suitable. Some products such as carbonated beverages and foods require containers that are resistant to the transfer of gases...
