18/400 CT Black Gold Metal Continuous Thread Caps

The 18/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Packaging engineers can assess Part 128530, the 18/400 CT Black Gold Metal Continuous Thread Caps, against the product, process, and presentation requirements of the program. Appropriate markets can include cosmetics, personal care, wellness, supplements, household, and specialty products. Final approval should follow closure-fit testing, seal evaluation, decoration review, and shipping trials.
