83/400 White Smooth Straight PP Cap / F217 Liner

Appropriate markets can include cosmetics, personal care, wellness, supplements, household, and specialty products. The 83/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. The commercial value of this packaging closure depends on disciplined component integration. Confirm thread fit, torque, liner performance, leakage resistance, and opening behavior on production containers. A thoughtful specification gives operations and brand teams the same target.
