Compatibility and Thread Systems
Our closures are compatible with industry standards such as DIN, GPI/GCMI, and FEA. Whether you're working with dropper bottles, perfume bottles, or nutritional supplements, we can assist in selecting the correct thread combination for a secure and reliable closure.
- DIN – the industrial measurement system used in Europe. The 18 in DIN18 refers to the neck size and is most commonly applied to dropper bottles ranging from 5 ml to 100 ml. A popular choice for essential oils, often combined with a tamper-evident sealing ring.
- GPI/GCMI – the American system with designations such as 22/400. The first number indicates the neck diameter, while the second refers to the height and thread style. You can easily find the correct closure by matching the GPI or GCMI code with the product details.
- FEA – crimp finish for perfume bottles, where the number refers to the outer neck diameter.
Perfectly Matched Packaging Combinations
A good closure does more than seal – it elevates your brand’s presentation. Choose from a wide range of colours, materials, and finishes, including black, white, metallic, or customised options. Easily combine with our glass bottles and jars for a complete packaging solution.
