38mm 38-400 Gold/Gold Metal Cap with Plastisol Liner

The 30W39D is a 38mm (38-400) gold electrolytic tinplate (tin coated steel) cap with a plastisol liner. This closure is typically used on glass bottles, jars, and jugs. This continuous threaded (CT) cap and has a gold exterior and interior with a knurled edge. Plastisol is a common liner that is used for applications such as food canning and vacuum packing, because it provides a hermetic seal (or airtight seal). It is recommended for high temperature applications (container must be able to withstand high temperatures as well).

Electrolytic tinplate caps are highly sought-after metal closures that are sometimes referred to as tin coated steel caps, which are manufactured from 73 lb. – 80 lb. x .20 lb. electrolytic tinplate metal. The coatings on these caps are FDA Compliant and contain no heavy metals and the tooling meets ISBT standards. The metal itself has been sized, coated, varnished, and waxed. Tin plate steel is sometimes used in place of lightweight mirrors due to its shiny or lustrous like mirror appearance. Tin-plate steel is available in various color options such as, white, gold, red, and yellow and is more competitively priced than other options. Most tinplate steel metal caps are colored and have a uniform color and coating application on the closure surface area; whereas, tin coated steel caps need a protective coating because they can corrode easily.
