24/400 White Smooth Straight PP Cap / PS Liner

The 24/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. It may fit briefs involving cosmetics, personal care, wellness, supplements, household, and specialty products. Product developers comparing packaging closure options can use Part 137750, the 24/400 White Smooth Straight PP Cap / PS Liner, as a focused candidate for qualification. Qualification should cover thread engagement, liner compatibility, line application, and expected storage conditions.
