UKPACK 1.4oz/40ml PP Cylinder Dual Chamber Airless Pump Bottle | Dual-Ended 2-in-1 10ml & 30ml Chambers with 3:1 Mixing Ratio

What this packaging is

Two formulas, one bottle — the 1.4oz/40ml PP Cylinder Dual Chamber Airless Pump Bottle splits into a 10ml and 30ml compartment with a built-in 3:1 mixing ratio, letting brands deliver a custom blend right at the point of use. The bottom-rotation mechanism gives consumers seamless access to each chamber, while dual vacuum airless technology shields both formulas from air and light degradation. Slim at 29.2mm wide and 197.1mm tall, it's a natural fit for serums, face oils, foundations, moisturizers, hair treatments, and sunscreens. Compatible with screen printing and hot stamping, this format opens up genuinely novel product storytelling for brands ready to go beyond single-formula packaging.

Why brands choose this

• Purpose-built for two-part formulas: The 3:1 split between the 30ml and 10ml chambers isn't just a packaging trick — it enables real formulation strategies like activator-plus-base or treatment-plus-serum pairings, giving product developers a format that does meaningful work at the moment of application.
• Dual vacuum airless protection for sensitive actives: Both chambers operate on independent airless vacuum systems, keeping oxygen and light away from each formula separately. That matters for high-performance skincare — serums, vitamin C oils, and reactive sunscreen actives all stay stable longer without preservative overloading.
• Decoration versatility supports strong shelf identity: Screen printing and hot stamping compatibility means brand teams aren't limited to a label slapped on a cylinder. The clean PP surface takes decoration well, giving this format — already distinctive for its dual-ended design — the finish options to match a premium or clinical brand aesthetic.
