Neck Compatibility for Roll-on Caps

To ensure proper sealing and performance, the neck finish of the roll-on cap must match that of the glass packaging. The European system for this is called DIN, where DIN18 is the standard for dropper bottles and other narrow-neck formats. This makes it easier to pair your roll-on caps with compatible glass bottles from our range.

Selecting the Right Roll-on Ball

Roll-on caps are available with three types of ball applicators: glass, stainless steel, and plastic. Glass is non-reactive and ideal for sensitive formulations such as essential oils. Stainless steel offers corrosion resistance and consistent, smooth application, while plastic is a more economical choice. Each roll-on applicator offers unique benefits depending on your product’s needs.

Request a Sample

To ensure your chosen roll-on cap fits your bottle and works with your formulation, we always recommend requesting a sample for internal testing. This allows you to verify compatibility and performance before scaling up.
