28/400 White Smooth Straight PP Cap / F217 Liner

This packaging closure deserves evaluation within the complete product and container system. Final approval should follow closure-fit testing, seal evaluation, decoration review, and shipping trials. The 28/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Likely development programs include cosmetics, personal care, wellness, supplements, household, and specialty products. The objective is a package that feels intentional at every point of use.
