Double Chamber Bottle

Double Chamber Bottle Manufacturer for Cosmetic & Skincare Packaging

Isolate sensitive active ingredients, simplify dual-step skincare routines, and elevate shelf presence with Hengbang’s OEM/ODM double chamber packaging solutions. Engineered in our 35,000-square-meter cleanroom facility, our dual-compartment systems completely eliminate chemical cross-contamination while ensuring consistent, leak-proof dispensing.
Whether your product line requires symmetric dual-pump distribution (15+15 ml) or asymmetric volume ratios (10+30 ml for oil-and-water treatments), we provide complete engineering support from mold customisation to mass production.

Formulation Integrity & Leak Prevention

Absolute Ingredient Separation

Physical isolation ensures that active components (such as Vitamin C, Retinol, AHA acids, or botanical oils) do not react or degrade prematurely during storage. Formulas are only combined at the precise moment of application.

Leak-Proof Seal & Transport Stability

Multi-component bottles carry higher shipping risks. We utilize precision-injection inner chambers combined with custom-fitted pump gaskets. Every lot undergoes strict vacuum leak-testing (-0.08 MPa for 30 minutes) to ensure zero cross-chamber bleeding or outer leakage during ocean and air transit.

Premium Double Chamber Essence Oil Bottle

Smooth Dispensing & Viscosity Matching

Our standard pump configuration delivers a controlled output of 0.23 cc per stroke. To prevent pump priming failures or uneven output, our engineering team assists buyers in calibrating the pump spring force and dip tube diameter based on your formula's specific viscosity (ranging from water-thin essences to heavy creams).

Automated Filling Line Compatibility

Both HB-S005 and HB-S003 series are designed with standardized neck dimensions and rigid base structures, allowing seamless integration with standard cosmetic automatic filling, plugging, and capping equipment.

Customizable Materials & Premium Surface Finishing

Material Selection Guide

MS (Methyl Methacrylate-Styrene): Provides crystal-clear transparency with heavy-wall glass-like aesthetics, high rigidity, and excellent impact resistance for outer shells and caps.

PETG: Offers superior chemical compatibility with aggressive active ingredients and essential oils, making it the ideal material for inner formula chambers.

PP & ABS: Highly durable, chemical-resistant polymers used for pump internal components and actuators to ensure long-term mechanical reliability.

OEM/ODM Surface Finishing

Custom Color Injection: Pantone-matched solid, translucent, or opaque colors.

Spray Coating: Soft-touch matte finish, high-gloss clear coat, or gradient spraying.
Hot-Stamping & Printing: High-precision silk-screen printing and metallic hot-foil stamping (Gold, Silver, Rose Gold).

Electroplating: Metallic finish for pump collars and decorative caps.

Procurement & Manufacturing Workflow

Specification & Compatibility Review:

Share your target volume ratios, formula viscosity, and artwork. Our packaging engineers verify component compatibility.

Sample Evaluation:

We dispatch stock samples within 3–5 days for your team to perform real-world formula stability, vacuum leakage, and drop testing.

Custom Pre-Production Samples:

Upon artwork approval and color matching, custom decorated samples are prepared within 7–10 days for final sign-off.

Mass Production & Quality Control:

Mass manufacturing is carried out in our Class 100,000 cleanrooms. Every batch is inspected for dimensional tolerances, pump dosing accuracy (+/- 0.02 cc), and decoration adhesion.

Export Packaging & Logistics:

Goods are packed in heavy-duty export cartons with protective tray partitions to prevent scratching during shipping.

FAQ

Q: Can we customize two different volume ratios in one bottle?

A: Yes. While symmetrical configurations like 15+15 ml (HB-S005) are popular for equal-dosage routines, asymmetric models such as 4+12 ml, 8+24 ml, or 10+30 ml (HB-S003) allow brands to pair high-potency concentrates or oils with larger-volume base serums.

Q: How do I ensure my formula will not react with the plastic materials?

A: We strongly recommend conducting full chemical compatibility testing. We provide unsealed testing samples (inner chambers, dip tubes, and pump engines) so your laboratory can perform 45-degree Celsius accelerated stability testing prior to mass production.

Q: What is the standard MOQ and lead time for custom OEM orders?

A: Our standard minimum order quantity (MOQ) is 10,000 pieces per design. Production lead time is typically 35 to 40 business days following pre-production sample approval and deposit receipt.

Q: Do you provide technical artwork templates (dielines)?

A: Yes. Upon receiving your project requirements, our design team will provide vector dielines (AI/PDF format) for the exact bottle model, enabling your design team to accurately place logo graphics and text.
