The Importance of Air Tightness Testing in Airless Bottles

For high-performance skincare and cosmetic packaging, air tightness testing is a critical step in airless bottle production. Without proper sealing, even the most advanced airless bottles can fail to protect sensitive formulations. At BEYAQI, strict air tightness testing ensures that every airless bottle delivers reliable performance, formula safety, and long-term stability for global beauty brands.

Why Air Tightness Matters in Airless Bottles

The core function of airless bottles is to prevent air from entering the container during use. Poor air tightness can lead to:

• Oxidation of active ingredients

• Reduced product efficacy

• Leakage during transportation

• Shortened shelf life

This makes air tightness testing essential for ensuring the functional integrity of airless packaging.

The Role of Air Tightness Testing in Formula Protection

Many skincare products—such as serums, creams, and active formulations—are highly sensitive to oxygen. Through professional air tightness testing, BEYAQI airless bottles help:

• Maintain a sealed internal environment

• Protect formulas from oxidation and contamination

• Reduce the need for excessive preservatives

• Preserve product performance from first to last use

Effective air tightness directly supports the value of airless packaging technology.

How BEYAQI Conducts Air Tightness Testing

During airless bottle production, BEYAQI integrates air tightness testing at multiple stages. Our testing methods include:

• Pressure and vacuum leakage tests

• Pump sealing and piston alignment checks

• Assembly integrity inspections

• Simulated transportation and usage testing

Each airless bottle must pass these air tightness tests before moving to final quality approval.

Preventing Leakage Through Air Tightness Testing

Leakage is one of the biggest risks in cosmetic packaging. By applying strict air tightness testing, BEYAQI ensures:

• Secure pump and nozzle connections

• Stable internal pressure control

• Reliable sealing during shipping and handling

• Reduced customer complaints and returns

This level of testing guarantees that BEYAQI airless bottles meet international quality standards.

Supporting Custom Designs with Reliable Air Tightness

Customization can introduce complexity to airless bottle production. BEYAQI maintains consistent air tightness even in custom airless bottles, including:

• Different bottle shapes and sizes

• Adjustable pump outputs

• PCR plastic and mixed-material structures

• Decorative finishes and branding

Every customized airless bottle undergoes the same air tightness testing as standard designs.
