Enquire / Sample Request

The GL18 White Child-Resistant Closure with Integrated EPE Liner (GL18CRCW-ILE) is a sealed storage closure combining a child-resistant opening mechanism with an integrated expanded polyethylene (EPE) foam liner disc, manufactured in PEHD and PP. Unlike the other CRC closures in the GL18 range — which incorporate dropper inserts, dispensing plugs, or self-seal membranes — the GL18CRCW-ILE contains no dispensing insert. It is a pure sealed cap designed to close and protect the bottle contents between uses, with the EPE liner creating a reliable mechanical seal against the glass bottle rim and the child-resistant mechanism preventing unsupervised access. This makes it the appropriate choice for products that are dispensed by a means other than the closure itself — for example, using a separate oral dosing syringe, dropper pipette, or measuring device — or for products requiring secure sealed storage between dispensing events where no integrated dispensing function is needed at the closure level.

Manufactured in two materials — PEHD (high-density polyethylene) for the inner cap body and PP (polypropylene) for the child-resistant mechanism — the GL18CRCW-ILE has a simpler construction than CRC closures incorporating flexible PELD inserts, reflecting the absence of a moulded dispensing component. As part of the GL18 system (also known as NW18 or DIN168), it is fully interchangeable across all GL18 glass dropper bottles in the BlueSky range — 5ml to 100ml, in both amber and clear glass. Contact BlueSky to confirm stock availability, MOQ, child-resistant certification status, and tamper-evident band options for this closure.

Sealed Storage Closure — No Integrated Dispensing Insert

The GL18CRCW-ILE is a pure sealed cap with no dropper, plug, or membrane insert — the bottle opening is fully accessible when the cap is removed, and sealed when it is replaced. This makes it the appropriate closure for products dispensed by a separate device such as an oral dosing syringe, dropper pipette, or measuring spoon, or for products requiring secure child-resistant sealed storage between uses where no integrated dispensing function is required at the closure level. Buyers specifying this closure for drop-by-drop dispensing applications should instead consider the GL18CRCW-IRD (rim dropper) or GL18CRCW-IVD (vertical dropper).

Child-Resistant Mechanism — Protection Without Dispensing Complexity

The GL18CRCW-ILE features a child-resistant opening mechanism requiring a specific combination of actions that young children are statistically unlikely to perform successfully, while remaining practical for adults. As a sealed cap rather than a dispensing closure, it provides child-resistant access protection in its simplest and most reliable form — without the additional complexity of a dropper or plug insert that could affect the child-resistance function. Please contact BlueSky’s team to confirm the child-resistant certification status of this closure before specifying for regulated applications.

Integrated EPE Foam Liner — Reliable Mechanical Seal

The EPE (expanded polyethylene) foam liner disc compresses against the glass bottle rim when the closure is tightened, creating a lightweight, chemically inert mechanical seal that prevents leakage, contamination, and evaporative loss between uses. EPE is the entry-level liner specification in the GL18 system — providing a reliable primary seal without additional barrier properties. For formulations requiring enhanced oxygen, moisture, or chemical barrier protection, BlueSky’s GL18 liner range includes PET, aluminium, PVDC, PTFE, and butyl rubber options in other closure configurations. Contact BlueSky’s team to discuss the most appropriate specification for your formulation.

Two-Material Construction — PEHD and PP

Unlike CRC closures incorporating flexible PELD dispensing inserts, the GL18CRCW-ILE uses just two materials: PEHD (high-density polyethylene) for the inner cap body, providing structural rigidity and broad chemical resistance; and PP (polypropylene) for the outer child-resistant mechanism, delivering the push-and-turn or squeeze-and-turn action required for opening. Both materials are widely specified for pharmaceutical and cosmetic closures and offer broad compatibility with liquid formulations. Formulation compatibility testing is recommended prior to production.

Universal GL18 Compatibility — 5ml to 100ml

The GL18CRCW-ILE is compatible with all GL18 glass dropper bottles in the BlueSky range — 5ml, 10ml, 15ml, 20ml, 30ml, 50ml, and 100ml — in both amber and clear glass. The GL18 neck standard maintains a consistent inner bore diameter of 10.65mm ± 0.15mm across all bottle volumes, meaning this closure specification does not change when bottle size changes within the range. For light-sensitive formulations requiring UV protection, amber glass is the recommended specification.

Simplest CRC Configuration in the GL18 Range

With no dispensing insert and a two-material construction, the GL18CRCW-ILE is the most straightforward child-resistant closure in the GL18 system — and for applications where no integrated dispensing function is required, this simplicity is a practical advantage. Fewer components means a more robust assembly with fewer points of potential failure, and a capping process that is straightforward to validate in a production environment.

Frequently Asked
Questions

Why does this closure have no dispensing insert?

The GL18CRCW-ILE is designed as a sealed storage closure — it protects the bottle contents between uses rather than facilitating a specific dispensing method. It is appropriate for products that are dispensed using a separate device such as an oral dosing syringe, dropper pipette, or measuring implement, or where the user accesses the bottle directly after removing the cap. For products requiring integrated drop-by-drop dispensing with child resistance, the GL18CRCW-IRD (rim dropper) or GL18CRCW-IVD (vertical dropper) are the appropriate specifications.

What is the difference between this closure and the GL18W-ILE?

Both closures use an integrated EPE foam liner and have no dispensing insert, but the GL18CRCW-ILE adds a child-resistant opening mechanism — requiring a specific combination of actions to open — that the standard GL18W-ILE does not have. The GL18W-ILE is appropriate for cosmetic and personal care products where child resistance is not required. The GL18CRCW-ILE is the correct specification where child access to the liquid contents presents a safety risk, or where child-resistant packaging is a regulatory requirement.

Does this closure meet child-resistant packaging regulatory requirements?

The GL18CRCW-ILE features a child-resistant mechanism designed to prevent access by young children. For applications where child-resistant packaging is a legal requirement — such as certain household chemical and medicinal products — please contact BlueSky’s team to confirm the certification status of this closure before specifying. Your regulatory advisor can confirm the applicable packaging legislation for your product category and market.

Does this closure also provide tamper evidence?

The child-resistant mechanism and any tamper-evident band are independent functions in the GL18 CRC closure system. Please contact BlueSky’s team to confirm whether a tamper-evident band option is available for this specific closure SKU. For products where both child resistance and tamper evidence are commercially or regulatorily required, confirming both functions at the specification stage is important before committing to production.
