28/400 White Child Resistant Pictorial PP Cap / PS Liner

This child-resistant closure pairs a defined specification with practical manufacturing and consumer-use
considerations. The 28/400 designation should be verified dimensionally because nominal finish names do not
guarantee identical sealing behavior. The format can serve pharmaceutical, nutraceutical, cannabis, veterinary,
and household-chemical packaging. Qualification should cover thread engagement, liner compatibility, line
application, and expected storage conditions. The objective is a package that feels intentional at every point of
use.
