The L338BKH5 stands as a robust black PP plastic 38-400 cap, engineered with child-resistant features and a universal heat induction seal (HIS) liner. Child-resistant caps are designed with a locking mechanism, requiring extra effort to open, meeting the standards set by regulatory agencies. Featuring a pre-inserted heat induction seal (HIS) liner, this cap ensures an airtight, tamper-evident seal when subjected to the appropriate heat induction sealing process. Compatible with both plastic and glass containers, the HIS liner, a metallic disk, offers enhanced security and preservation capabilities.
