PET Bottles GL18 / DIN168

PET bottles GL18 / DIN168 provide a versatile packaging format for liquid pharmaceutical and healthcare products.

The neck configuration can support compatible closures and dosing components. Therefore, manufacturers can build different packaging systems around the same neck concept.

GL18 / DIN168 Packaging Systems

GL18 and DIN168 formats are widely associated with pharmaceutical bottle-and-closure systems.

The neck geometry must match the selected cap or dispensing component. In addition, sealing surfaces should be evaluated as part of the complete package.

Compatible Closures

Depending on the configuration, PET bottles in this group can be considered with compatible screw caps.

Selected tamper-evident or child-resistant solutions may also be available for suitable bottle designs.

However, final compatibility must always be confirmed with the actual components.

Dosing Components

GL18/DIN168 packaging can support several dispensing concepts.

These may include dropper plugs, pipettes or dosing pumps where the component design is compatible with the selected bottle.

As a result, the same neck family can serve different product applications.

Samples and Testing

Customers can request technical information and samples from Farmmash.

Testing helps confirm bottle-to-closure fit, sealing and dispensing functionality before serial production.
