US finishes are available through either the Glass Packaging Institute (GCMI finishes), Washington, DC, or glass manufacturers as special finishes e.g. OIG (Owens Illinois). Some of the more important finishes are as follows ... 

The size of CT closures is specified by the nominal outside dimension of the container opening in millimeters, plus a number that represents the style of finish. Both container and closure finishes are standardized so that, at least in theory, a closure of a given size and style should fit any bottle of that same size and style, from any manufacturer. U.S. closure standards have been established by the Closure Manufacturers Association, standards for glass bottles by the Glass Packaging Institute, and for plastic bottles by ASTM International (Fig. 11.8). Common closure diameters are 22-120 mm. 

Omitting the construction and demolition debris from the calculations, the composition (by volume this time) is as follows paper and paperboard 50%, plastics 14%, metals 12%, glass 4%, organics 6%, and miscellaneous 14%. All plastic packaging (post-consumer, industrial, commercial, and institutional) represented about 8% of the overall refuse. It is a reasonable assumption that the composition of plastics discarded in landfills is a reflection of the quantities produced for packaging applications the commodity plastics polyethylene, polypropylene, polystyrene, and poly(vinyl chloride) should be well represented (see Ethylene POLYMERS PROPYLENE Polymers (PP) Styrene Polymers Vinyl Chloride Polymers).
