Calaso 18-DIN Monomaterial Dropper Cap

What this packaging is

All-PP construction makes this dropper cap fully monomaterial — a detail that matters for brands navigating end-of-life packaging commitments. The 18-DIN Monomaterial Dropper Cap from Calaso is a threaded PP closure designed for precision dispensing in tincture applications, where dose control and leak resistance are non-negotiable. The ribbed grip and straight-sided tall profile give it a clean, professional look that reads well in wellness and apothecary contexts. Sourced from the Netherlands, where Calaso's closure expertise is built into every spec. With minimums starting at just 50 units, it's genuinely accessible for small-batch tincture brands or formulation testing.

Why brands choose this

• Minimums of 50 units: accessible for small-batch brands: At just 50 units MOQ, this cap opens the door for emerging tincture brands, apothecary startups, or limited-edition launches to source a quality, professionally finished closure without overcommitting on inventory.
• Dose-control design meets the tincture category ritual: The ribbed grip and dropper format directly support the measured-drop dispensing ritual that tincture consumers expect — reducing spillage and over-dispensing, which matters especially in CBD, herbal supplement, and functional wellness markets where precise dosing is a key brand promise.
• Monomaterial PP build simplifies end-of-life handling: As clean beauty and wellness brands face increasing pressure around packaging disposal, a single-material PP closure removes the complexity of mixed-material separation — making it easier to communicate responsible packaging choices to ingredient-conscious consumers.
