Calaso 18-DIN Monomaterial Dropper Cap

What this packaging is

Single-material construction sets this dropper cap apart — the 18-DIN Monomaterial Dropper Cap is built entirely from polypropylene (PP), keeping the component stream clean and simple for brands thinking ahead about end-of-life. Designed for DIN18 neck finishes, it pairs with glass dropper bottles used for tinctures, face serums, and hair oils, delivering the precise, controlled dispensing those formats demand. Manufactured in the Netherlands by Calaso, a specialist in glass and closure systems, this component brings European design and manufacturing credibility to your supply chain. With an MOQ of just 50 units, it's genuinely accessible for small-batch tincture brands or early-stage product development.

Why brands choose this

• 50-unit MOQ removes the barrier to entry: With a minimum order of just 50 units, this cap is one of the most accessible dropper closures on the market — purpose-built for craft tincture brands, herbalists, or anyone testing a new SKU without committing to bulk inventory.
• Monomaterial PP design simplifies the end-of-life story: Made entirely from a single polypropylene material stream, this dropper cap is easier to sort and process than multi-material closures — a straightforward, honest packaging choice for brands that want cleaner sourcing without greenwashing.
• DIN18 thread fit locks in precision dispensing for tinctures: The standardized DIN18 neck finish creates a secure, consistent seal that matters when your consumer is dosing a CBD tincture or botanical extract drop by drop — the format reinforces the ritual and builds trust in your product at the moment of use.
