Dual Chamber Airless Bottle — 2x10ml & 2x15ml | OEM Packaging

Product Overview

This PETG dual chamber airless bottle houses two completely separate internal cartridges inside a single square-profile body. Each chamber has its own independent airless pump, so two different formulations — such as a vitamin C serum and a hyaluronic acid moisturizer, or a day cream and a night cream — stay isolated until the moment of dispensing. The vacuum mechanism in each chamber prevents air from contacting the formula, which helps preserve oxidation-sensitive active ingredients and reduces the need for heavy preservative systems.

The outer body is made from PETG (Polyethylene Terephthalate Glycol), which offers higher optical clarity than standard PP airless bottles and better impact resistance than AS or PMMA. PETG is also chemically stable across a wide pH range, making it well-suited for a dual chamber application where each side may contain formulas with different acidity levels. The bottle is available in two capacity configurations: 2x10ml (20ml total, suited for travel kits, subscription box samples, or deluxe trial sets) and 2x15ml (30ml total, suited for retail counter sets, gifting, or 30-day targeted treatment programs).

Lumlun manufactures this bottle on a pure OEM basis with a minimum order quantity of 10,000 units. The pump configuration is flexible — you can pair two lotion pumps, or combine one lotion pump with one fine mist spray nozzle for multi-step skincare kits. The process begins with a WhatsApp conversation to confirm capacity, pump type, body color, and print layout. From artwork approval to shipment, typical lead time is 35–45 days due to the structural complexity of the dual-cartridge assembly. No ODM or stock inventory — every order is produced to your specifications.

Packaging Specifications

Customization

Every bottle is produced to your brand specifications. The PETG body color is set through injection coloring to your Pantone reference — transparent tints, frosted effects, or solid opaque finishes are all achievable. The square profile provides four flat surfaces for silk screen printing, making it well-suited for detailed brand marks, ingredient callouts, or usage instructions on separate panels. Hot stamping adds metallic foil accents for logos or decorative borders. Metallization creates a reflective chrome or satin metal effect across the body. Gradient color transitions can run vertically from the base to the shoulder. The pump actuator housing can be color-matched or contrasted with the body. Share your artwork files and Pantone codes via WhatsApp, and our team will prepare a digital mock-up within 48 hours for your review before sample production begins.
