An improved plastic laminated structure, a method to make that structure and use of that structure as a cover for a moisture-resistance electronic utility meter register. The structure is formed by providing a plastic layer to which is laminated on one side by means of an adhesive a water vapor barrier film of polychlorotrifluoroethylene.

Process to produce a cover for a utility meter register

A hood suitable for protection against decompression and toxic fumes, prepared using a laminar structure of polyimide, two or more layers of fluoropolymer and heat sealable polymer that affords the heat resistance of polyimide with a markedly lower internal noise level, ease of fabrication and resistance to etching by flame. An improved neck seal is also provided.
