Calaso HDPE 18-DIN Child Resistant Tamper Evident Screw Cap with 1.6mm Vertical Dropper

What this packaging is

Precision-dosed and double-protected, the HDPE 18-DIN Child Resistant Tamper Evident Screw Cap with 1.6mm Vertical Dropper is engineered for brands where safety and accurate dispensing are non-negotiable. The DIN18 II thread closure combines a child-resistant PP cap with a tamper-evident HDPE ring and a natural LDPE vertical dropper insert — delivering a controlled 1.6mm orifice ideal for face serums, hair oils, and wellness treatments. Manufactured in Europe, this closure reflects the precision and quality standards that performance-driven brands depend on. With an MOQ of just 50 units, it's genuinely accessible for emerging brands or limited-edition product launches building toward retail-ready safety compliance.

Why brands choose this

• Accessible minimums for small-batch and indie brands: At just 50 units MOQ, this closure is one of the most accessible entry points in safety-certified dropper packaging — letting emerging brands, indie wellness labels, and limited-edition launches meet child-resistant compliance without overcommitting on inventory.
• Dual-layer safety that meets regulatory and retail expectations: The combination of a child-resistant DIN18 II screw mechanism and a tamper-evident Type II HDPE ring addresses both consumer protection requirements and retailer shelf standards — a critical pairing for face serums and hair oils moving into specialty or mass retail channels.
• 1.6mm dropper orifice delivers the dose-control consumers expect: In a market where over-application frustrates consumers and erodes brand trust — especially for high-value serums and oils — a fixed 1.6mm vertical dropper insert provides consistent, drop-by-drop dispensing that reinforces product efficacy and supports a premium use ritual.
