GL18 White Tamper-Evident Closure with Integrated EPE Liner

The GL18 White Tamper-Evident Closure with Integrated EPE Liner (GL18TEW-ILE) is a sealed storage closure combining a tamper-evident opening mechanism with an integrated expanded polyethylene (EPE) foam liner disc, manufactured entirely in PEHD. The integral tamper-evident ring — moulded as part of the cap body in a single injection moulding step — provides visible first-open evidence confirming the product has not been accessed prior to purchase, while the EPE foam liner creates a reliable mechanical seal against the glass bottle rim when the closure is tightened. Like the standard GL18W-ILE, this closure contains no dispensing insert — it is a pure sealed cap designed to close and protect the bottle contents between uses, with tamper evidence added for retail product applications where consumer assurance at point of purchase is a commercial requirement.

The single-material PEHD construction — with no flexible PELD component — reflects the absence of a moulded dispensing insert, resulting in a straightforward, robust assembly suited to retail cosmetic, personal care, and general consumer wellness products where the primary closure requirements are tamper evidence, a reliable seal, and a clean retail presentation. As part of the GL18 system (also known as NW18 or DIN168), the GL18TEW-ILE is fully interchangeable across all GL18 glass dropper bottles in the BlueSky range — 5ml to 100ml, in both amber and clear glass — without any change in closure specification. For formulations with specific barrier requirements beyond the basic EPE seal, BlueSky’s GL18 liner range provides enhanced options including PET, aluminium, PVDC, PTFE, and butyl rubber.
