BOV Facial Mist and Toner Spray Filling Machine

AILE provides complete bag on valve aerosol filling solutions for facial mist, toner spray, thermal water spray, moisturizing mist and other premium skin care aerosol products.

According to your required production capacity, AILE can provide either a semi-automatic aerosol filling machine or a fully automatic filling line. The complete solution can cover BOV valve placement, compressed air or nitrogen filling, valve crimping, liquid filling, inspection, actuator pressing and cap pressing.

Suitable Products

Our facial mist aerosol filling equipment can be customized for:

• Facial hydrating mist
• Toner spray
• Thermal water spray
• Moisturizing facial spray
• Soothing facial mist
• Post-sun cooling spray
• Sensitive skin spray
• Other water-based cosmetic sprays

The final equipment configuration depends on the product formula, filling volume, aerosol can, BOV valve and required production capacity.

Why Use Bag on Valve Packaging for Facial Mist?

Premium facial mist products often require a soft spray, controlled dispensing and hygienic packaging. Bag on valve packaging provides a practical solution for these requirements.

Formula and Pressure Gas Separation

The cosmetic formula is filled inside the inner bag, while compressed air or nitrogen remains between the bag and the aerosol can. This structure prevents direct contact between the formula and the pressure gas.

Compressed Air or Nitrogen

A BOV product can use purified compressed air or nitrogen instead of liquefied flammable propellants such as LPG or DME. The suitable pressure gas is selected according to the product, valve and packaging requirements.

Fine and Consistent Spray

The formula, BOV valve, actuator, nozzle and internal pressure can be matched to produce a soft and continuous facial mist. The spray result is not determined by the filling machine alone. Testing the complete package before production is recommended.

360-Degree Dispensing

With a suitable BOV valve and actuator, the product can be sprayed from different angles, improving the user experience.

High Product Evacuation

Pressure outside the bag gradually compresses the bag during use, helping reduce the amount of formula remaining inside the package.

Facial Mist BOV Filling Process

The standard BOV filling process is:

1. Empty aerosol can feeding
2. BOV valve placement
3. Compressed air or nitrogen filling under the valve cup
4. Valve crimping
5. Liquid filling through the valve
6. Weight and pressure inspection
7. Actuator pressing
8. Cap pressing
9. Coding, labeling and packaging

During production, the pressure gas is filled between the aerosol can and the inner bag while the valve is crimped. The facial mist formula is then filled into the bag through the valve. The formula and pressure gas remain separated during storage and product use.

Semi-Automatic BOV Filling Solution

The semi-automatic bag on valve machine is suitable for:

• New product development
• Trial production
• Small-batch manufacturing
• Start-up cosmetic brands
• Frequent product or package changes
• Manufacturers with limited factory space

A typical semi-automatic line can include:

• BOV gas filling and crimping machine
• Through-the-valve liquid filling machine
• Air compressor
• Product storage tank
• Manual actuator pressing machine
• Manual cap pressing machine
• Optional pressure and leak testing equipment

The operator manually places the aerosol can and BOV valve into the machine. The machine first fills compressed air or nitrogen and crimps the valve. The formula is then filled into the inner bag through the valve. This solution requires a lower initial investment and provides greater flexibility for different aerosol can sizes and filling volumes.

Fully Automatic BOV Filling Line

The fully automatic line is designed for cosmetic manufacturers and aerosol contract fillers requiring continuous production, reduced labor and stable output.

A complete automatic aerosol can filling machine line can include:

• Automatic aerosol can feeding
• Automatic BOV valve feeding and placement
• Automatic gas filling and valve crimping
• Automatic through-the-valve liquid filling
• Online weight checking
• Pressure or leak inspection
• Automatic actuator pressing
• Automatic cap feeding and pressing
• Coding and labeling equipment
• Cartoning or case-packing equipment

The complete BOV equipment can be customized according to filling volume, aerosol can diameter and height, BOV valve specification, required production speed, inspection requirements, and factory layout.

Semi-Automatic or Fully Automatic?

AILE will recommend the appropriate automation level according to your expected output, factory conditions and investment plan.

Simple Formula Preparation

For low-viscosity facial mist and toner spray products, the preparation system may include a stainless steel mixing or storage tank, filtration system, sanitary transfer pump, and product delivery pipeline.

SS304 or SS316L product-contact parts can be selected according to the cosmetic formula and production requirements. Complex emulsifying equipment is normally unnecessary for simple water-based facial mist formulas unless required by the customer's production process.

Key Factors Affecting Spray Quality

A successful facial mist product depends on the complete filling and packaging system. The main factors include:

• Formula viscosity
• BOV valve structure
• Actuator and nozzle design
• Internal gas pressure
• Filling volume
• Aerosol can size
• Valve crimping quality

Before equipment production, customers are encouraged to provide aerosol cans, BOV valves, actuators, caps and product samples for compatibility testing.

Optional Inspection and Packaging Equipment

The filling line can also be connected with an online weight checker, pressure detection equipment, leak testing equipment, aerosol water bath, actuator pressing machine, cap pressing machine, inkjet coding machine, labeling machine, and cartoning and case-packing equipment.

The final inspection method should be selected according to the aerosol package, product characteristics and customer quality-control requirements.
