3.4oz/100ml Dual Chamber Airless Pump Bottle | 2-in-1 80ml PETG Base & 20ml PP Booster Snap-On System with 4:1 Mixing Ratio

What this packaging is

Two formulas, one press — the 3.4oz/100ml Dual Chamber Airless Pump Bottle from FS Korea combines an 80ml PETG base with a 20ml PP booster in a 4:1 mixing ratio that activates at the point of application. Manufactured in South Korea, where precision engineering meets cosmetic innovation, this airless pump system keeps both chambers sealed and contamination-free until the moment of use. Built for face moisturizers and hair treatments where blending actives on contact genuinely changes efficacy, it's also available with PCR content for brands building toward more responsible material sourcing. Decoration-ready with silk screen and hot stamp options.

Why brands choose this

• 4: 1 ratio dispensing for on-contact blending: Mixing two separate formulas at the moment of application isn't just a technical feature — it's a product story. This format lets brands formulate with ingredients that shouldn't coexist in storage, opening doors to fresher actives and more credible efficacy claims for face moisturizers and hair treatments.
• Airless dual-chamber keeps both formulas stable: Airless packaging is a proven signal of ingredient integrity, and having two independent airless chambers in a single bottle takes that further. No air exposure means no oxidation risk for either formula — a genuine functional benefit that also resonates with the growing consumer demand for preservative-conscious formulations.
• PCR-compatible for brands with material goals: This bottle is available with PCR content, giving sustainability-minded brands a path to reduce virgin plastic use without switching formats. It's a straightforward way to align a technically differentiated product with environmental commitments, particularly relevant as clean beauty and responsible sourcing continue to shape purchase decisions in skincare and haircare.
