Plastic Caps, 24/400 - 38/400 Black Phenolic Cone Lined Caps
Product Specs & Information
Style:Cone Caps
Size(s):
Cap Option:Cone Caps
Quick Answers About 24/400 - 38/400 Black Phenolic Cone Lined Caps
- What type of liner do these caps have, and what does it do? These caps are lined with a cone liner (also called Polyseal), which is a molded LDPE cone that wedges tightly into the neck of the bottle and seals against both the rim and the inner wall. It stands up to essential oils, solvents, acids, and other harsh chemicals without loosening or gluing shut over time.
- Which containers are a match for these caps? Each cap code goes with a specific cap size: E (24/400), H (28/400), J (33/400), and K (38/400). A cap code pairs closures and containers using the neck finish, the inner neck diameter, and other factors, so the containers that match depend on the cap size. Container options include white HDPE f-style jugs, amber glass pharmaceutical round bottles, amber glass round bottles, and clear glass rounds, plus many more, depending on cap size. The full list is under Add-Ons on this page, and the Cap Code chart shows every match.
- What neck finishes are available? This page offers 4 neck finishes: 24/400, 28/400, 33/400, and 38/400.
- Can I add a tamper evident shrink band? Many containers can be paired with a PVC shrink band for a visible tamper-evident seal. Check the Add-Ons for this item or the shrink band compatibility chart to see which bands fit.
- What are these typically used for? These black phenolic cone lined caps are commonly chosen for essential oils, solvents, and other liquid products. Compatibility depends on your product, so run your own tests before committing to a full production run.
Product Description:
Harsh chemistry calls for a cone liner, and these black phenolic cone lined caps use a molded LDPE cone, also called Polyseal. The cone presses into the bottle neck and seals against the rim and the inner wall at once. Essential oils, solvents, acids, and other harsh chemicals do not make it loosen or seize over time. Four neck finishes, 24/400 through 38/400 (cap codes E, H, J, and K), fit amber glass pharmaceutical rounds, amber glass rounds, clear glass rounds, and white HDPE f-style jugs. Essential oils and solvents could be a good fit. The Add-Ons list every compatible container.
