83/400 White Smooth Straight PP Cap / PS Liner

Nominal finish compatibility is only the first screen; thread profile, land geometry, torque, and liner compression decide sealing. Part 138140 gives development teams a focused basis for testing this packaging closure. Product teams may consider it for cosmetics, personal care, wellness, supplements, household, and specialty products. Use filled-package trials to qualify fit, liner compression, leakage, and repeated opening performance. Good component decisions here can prevent costly changes during scale-up.
