The 30W89A is a 89mm 89-400 Clear Aluminum Tinplate (tin coated steel) Cap with PE Foam Liner that is a great general purpose closure. The cap is ideal for powders and non-acidic food products and consumer products such as jar candles and honey.

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.

Cap Liner Type:

Three-Ply Co-extruded PP/LDPE/PP Foam Liner Composition
This one-piece, three-ply co-extruded liner incorporates a closed cell foam core of Low Density Polyethylene (LDPE) sandwiched within polypropylene (PP) layers. This results in a chemically fused, single polymeric product. Symmetrical construction: Either side serves as the liner face. Chemically inert, odorless, tasteless and dust-free, this liner offers good resistance to acids, alkalies, slow solvents, alcohol, oils and aqueous products. Poor resistance to active hydrocarbon solvents. Recommended for sealing hot filled products that may be subjected to temperatures up to 190° F.
