1.7oz/50ml Dual Chamber PETG Airless Pump Bottle | 40ml Top Bottle & 10ml Bottom Stacked System with 4:1 Mixing Ratio

What this packaging is

A 4:1 mixing ratio built into a single airless pump — that's the standout engineering behind this 50ml Dual Chamber PETG Airless Pump Bottle. The stacked dual-chamber system dispenses two formulas simultaneously: 0.2cc from the 40ml top chamber and 0.05cc from the 10ml bottom, keeping actives separate until the moment of application. Built from PETG with PP and ABS components, it's manufactured in South Korea — a region known for precision cosmetic packaging and skincare innovation. Compatible with silk screen printing and hot stamping, and available with PCR content for brands with sustainability goals. Purpose-built for face moisturizers, eye creams, and hair treatments where multi-phase formulas deserve packaging that matches their sophistication.

Why brands choose this

• Engineered 4: 1 dosing for multi-phase formulas: The built-in dual-chamber system dispenses two distinct formulas at a calibrated 4:1 ratio with every pump — no guesswork, no cross-contamination. This is a genuine technical differentiator for brands developing two-part actives, A/B serums, or blended treatment systems.
• South Korea manufacturing signals skincare credibility: Produced in South Korea, one of the most respected origins for advanced cosmetic packaging, this component carries real equity for prestige skincare positioning — and reflects the engineering precision the dual-chamber mechanism demands.
• Available with PCR content for sustainability commitments: Brands working toward lower-impact packaging can source this bottle with PCR material included, supporting material reduction goals without sacrificing the airless functionality or the clean cylindrical aesthetic that works across moisturizers, eye creams, and treatment formats.
