20/400 White Smooth Straight PP Cap / PS Liner

The commercial value of this packaging closure depends on disciplined component integration. The 20/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Before release, evaluate application torque, seal integrity, removal force, and distribution performance. The format can serve cosmetics, personal care, wellness, supplements, household, and specialty products. The objective is a package that feels intentional at every point of use.
