83/400 White Smooth Straight PP Cap / Unlined

For a production-intent package, the 83/400 White Smooth Straight PP Cap / Unlined (Part 138150) offers a defined packaging closure rather than a generic starting point. Its application range extends to cosmetics, personal care, wellness, supplements, household, and specialty products. Even on the same neck finish, liner thickness and thread engagement can materially change seal performance. Prototype with the intended container and product to verify torque range, sealing, and consumer handling.
