GL18 White Child-Resistant Closure with Self-Seal

ISO 8317 is the international standard for child-resistant packaging. It requires that a closure be tested with panels of children aged 42–51 months and adults aged 50–70 years, demonstrating that a specified percentage of children cannot open the package within a set time, while a specified percentage of adults can. Certification to ISO 8317 is a regulatory requirement for child-resistant pharmaceutical packaging in the UK and EU, and provides a verifiable, standardised safety credential that generic “child-resistant” claims cannot substitute. The GL18CRCW-SSC carries ISO 8317 certification.

The CRC mechanism operates independently of a tamper-evident band — child resistance and tamper evidence are separate functions in this closure system. A tamper-evident band option may be available for this closure; please contact BlueSky’s team to confirm. For OTC pharmaceutical products where both child resistance and tamper evidence are required, specifying both functions in a single closure provides the most compliant and commercially clean packaging solution.

Yes. The GL18CRCW-SSC is compatible with GL18 dispensing accessories including vertical droppers, rim droppers, syringe plugs, pourers, and orifice reducers — all of which fit within the GL18 neck and work with all four cap shapes in the system. For paediatric oral liquid medicines where child resistance and syringe-based dosing are both required, the combination of the CRC closure and integrated syringe plug is the appropriate specification. Please contact BlueSky’s team to confirm accessory compatibility with your specific combination.

In the UK, child-resistant packaging is a legal requirement for medicinal products under the Human Medicines Regulations 2012, and for certain household chemical products under CHIP and CLP regulations. In the EU, equivalent requirements apply under the Medicinal Products Directive and CLP Regulation. Beyond legal requirements, child-resistant closures are increasingly specified voluntarily by brands supplying concentrated nutritional supplements, botanical preparations, and CBD products — particularly where the target consumer includes households with young children.
