How to Customize a Perfume Filling and Crimping Line: Information and Sample Requirements

Choosing a perfume packaging eqipment involves more than confirming whether the bottle holds 30 ml, 50 ml, or 100 ml.

Perfume bottles vary widely in shape, bottle-neck structure, spray-pump size, decorative collar, and outer-cap design. Two bottles with the same nominal capacity may require completely different filling nozzles, conveyor guides, crimping heads, and cap-pressing molds.

Before customizing a perfume filling and crimping line, the equipment manufacturer needs to evaluate the perfume liquid, bottle, spray pump, decorative collar, outer cap, target output, and factory conditions.

This guide explains what information and samples a perfume manufacturer should provide when requesting a customized packaging solution.

What Does a Perfume Filling and Crimping Line Do?

A perfume filling and crimping line is used after the perfume has been mixed, cooled, filtered, and stabilized.

It does not manufacture the perfume formula. Instead, it fills the finished fragrance into bottles and completes the bottle-closing process.

A typical perfume packaging line may include:

1. Empty bottle loading or feeding
2. Vacuum perfume filling
3. Spray-pump placement
4. Spray-pump crimping
5. Decorative collar pressing
6. Outer-cap installation
7. Bottle labeling
8. Batch coding
9. Finished-product collection or cartoning

The final configuration depends on the bottle structure, closure components, production capacity, and required level of automation.

1. Perfume Liquid and Filling Requirements

The first step is to confirm whether the perfume is suitable for the proposed filling system.

The customer should provide:

• Product type
• Alcohol concentration
• Liquid viscosity
• Filling volume
• Required liquid level
• Whether the liquid foams easily
• Whether it contains particles or sediment
• Whether multiple fragrances will use the same line
• Cleaning requirements between fragrance changes

Most alcohol-based perfumes are low-viscosity liquids. Vacuum filling is commonly used because it controls the visible liquid level inside the bottle.

This is particularly useful for transparent perfume bottles. Minor variations in the internal volume or wall thickness of glass bottles can produce different liquid levels when filling only by volume. A vacuum filling system removes excess liquid and helps keep the final liquid levels consistent.

However, vacuum filling is not suitable for every product. The viscosity, volatility, foaming characteristics, and required filling result should be confirmed before selecting the machine.

Example Liquid Information

Product: Alcohol-based perfume
Alcohol concentration: Approximately 80%
Viscosity: Below 10 cps
Bottle capacity: 50 ml
Required liquid level: 25 mm below the bottle opening

The customer does not necessarily need to disclose the complete perfume formula, but sufficient information must be provided to evaluate material compatibility and filling performance.

2. Perfume Bottle Information

Bottle capacity alone is not enough to customize a perfume packaging line.

For each bottle format, the customer should provide:

• Nominal bottle capacity
• Overall bottle height
• Maximum bottle width
• Bottle thickness
• Bottle-bottom dimensions
• Bottle-opening inner diameter
• Bottle-opening outer diameter
• Bottle-neck height
• Bottle material
• Bottle shape
• Empty bottle weight

Photos should show the front, side, bottom, and bottle opening. A dimensional drawing is also helpful.

Why Does Bottle Shape Matter?

Round, square, flat, and irregular-shaped perfume bottles behave differently on a conveyor.

Tall or narrow bottles may become unstable during transportation. Flat bottles may need side guides to maintain the correct orientation. Irregular bottles may require customized positioning or holding components during filling and crimping.

The equipment manufacturer uses the bottle information to determine:

• Conveyor width
• Guide-rail position
• Bottle-separating mechanism
• Filling-nozzle position
• Bottle holding and positioning method
• Changeover requirements between formats

Physical bottle samples are recommended before the final machine design is confirmed.

3. Bottle-Opening and Neck Dimensions

The bottle opening affects both the filling and crimping processes.

Important dimensions include:

• Bottle-opening inner diameter
• Bottle-opening outer diameter
• Bottle-neck height
• Crimping neck diameter
• Neck profile
• Distance between the bottle shoulder and opening

The inner opening must be compatible with the filling nozzle and the spray-pump dip tube. The external neck structure must match the spray pump and crimping head.

Even if two spray pumps are both described as 15 mm perfume pumps, differences in the bottle-neck profile or aluminum collar can affect the crimping result.

The bottle, spray pump, and crimping head must therefore be evaluated as one complete system.

4. Spray-Pump Information

The spray pump is one of the most important components when customizing a perfume crimping machine.

The customer should provide:

• Spray-pump type
• Crimping diameter
• Aluminum collar outer diameter
• Aluminum collar height
• Total pump height
• Center-stem dimensions
• Dip-tube diameter
• Dip-tube length
• Required crimping appearance
• Complete physical samples

The customer should also confirm whether the dip tube is already cut to the correct length.

If the tube is too long, it may bend excessively or prevent the pump from sitting correctly on the bottle. If it is too short, the finished bottle may not dispense all the perfume.

What Is Spray-Pump Crimping?

During crimping, the machine presses and forms the aluminum section of the spray pump around the bottle neck. The result must be tight enough to secure the pump and prevent leakage without damaging the glass bottle or deforming the pump.

The crimping head must be manufactured or adjusted according to the actual pump and bottle-neck dimensions. A photo is normally insufficient for final customization.

5. Decorative Collar Information

Many perfume bottles have a decorative collar installed over the crimped spray pump. This component covers the crimped area and improves the appearance of the finished bottle.

The customer should provide:

• Collar inner diameter
• Collar outer diameter
• Collar height
• Collar material
• Collar shape
• Required pressing depth
• Required final position
• Whether the collar is easily scratched or deformed
• Physical samples

The collar is normally installed by downward pressing rather than crimping. A customized pressing mold may be required to prevent surface damage and control the final installation depth.

If several collar formats will use the same line, samples of every format should be provided.

6. Outer-Cap Information

The decorative collar and outer cap are different components.

A typical perfume bottle may contain:

• Spray Pump: Dispenses the perfume and is secured to the bottle by crimping.
• Decorative Collar: Covers the crimped area and is installed by pressing.
• Outer Cap: Protects the spray pump and completes the bottle appearance.

For the outer cap, the customer should provide:

• Cap height
• Inner and outer diameter
• Cap shape
• Cap material
• Installation method
• Required pressing force
• Whether the cap has a fixed orientation
• Whether the cap is magnetic
• Physical samples

The customer should specify whether the outer cap is:

• Snap-on
• Press-fit
• Friction-fit
• Magnetic
• Direction-sensitive

A simple round snap-on cap may be installed using a standard pressing system. Square, magnetic, or direction-sensitive caps may require additional positioning mechanisms.

7. Required Production Capacity

The required production speed determines the number of filling heads, capping configuration, feeding method, and level of automation.

The customer should provide:

• Required bottles per minute
• Required bottles per hour
• Daily production target
• Working hours per day
• Number of bottle formats
• Output required for each format
• Frequency of bottle changeovers
• Expected future capacity

The output of a complete production line is determined by its slowest station.

For example, a filling section may process 40 bottles per minute, but if the crimping and collar-pressing section processes 20 bottles per minute, the practical output of the line will be approximately 20 bottles per minute.

The complete production process should therefore be considered when specifying the required output.

8. Manual Placement or Automatic Feeding?

The customer should decide whether the spray pumps, decorative collars, and outer caps will be placed manually or fed automatically.

Manual Component Placement

Operators manually place the pump, collar, or cap onto each bottle before it enters the corresponding working station.

This configuration may be suitable when:

• Production output is relatively low
• The factory has available operators
• Bottle formats change frequently
• Pumps or caps are irregularly shaped
• The initial equipment budget is limited

Automatic Component Feeding

Vibratory bowls, elevators, or customized sorting systems automatically orient and feed the components.

This configuration may be suitable when:

• Higher production capacity is required
• The packaging components are dimensionally consistent
• The same bottle format is produced for long periods
• The factory wants to reduce manual handling

Automatic feeding systems must be designed according to actual samples. Highly decorative, easily scratched, irregular, or direction-sensitive components may require specialized feeding structures.

9. Is Bottle Cleaning Required?

Empty perfume bottles may contain dust or small particles from storage, transportation, or glass manufacturing.

Before filling, the customer should confirm whether bottle cleaning is required.

Available options may include:

• Air rinsing
• Vacuum cleaning
• Negative-ion air cleaning
• Liquid rinsing
• Manual bottle cleaning

The suitable method depends on the bottle-opening size, cleanliness requirement, factory process, and applicable production standard.

If bottle cleaning is required, it should be included when planning the line layout and production capacity.

10. Labeling and Coding Requirements

If labeling is included, the customer should provide:

• Bottle shape
• Bottle dimensions
• Label dimensions
• Label material
• Label roll direction
• Label position
• Number of labels per bottle
• Required labeling accuracy
• Physical label rolls

Possible labeling processes include:

• Wrap-around labeling for round bottles
• Single-side labeling
• Front-and-back labeling
• Bottom labeling
• Tamper-evident labeling

For batch coding, the customer should confirm:

• Required printed information
• Number of text lines
• Printing position
• Bottle or label surface material
• Ink color
• Date format
• Whether variable data are required

11. Factory Conditions

Before confirming the machine configuration, the customer should provide information about the installation site.

Required factory information includes:

• Country and installation location
• Local voltage
• Electrical frequency
• Single-phase or three-phase power
• Available compressed-air pressure
• Installation-area dimensions
• Door and access dimensions
• Required conveyor direction
• Upstream and downstream equipment
• Local safety requirements

Because perfume often contains a high percentage of alcohol, the customer should also confirm whether the production area has specific requirements for ventilation, electrical components, grounding, or explosion protection.

Writing only “explosion-proof required” is not sufficient. The customer should provide the applicable local standard and identify the classified production area.

Why Are Physical Samples Necessary?

Photos and drawings are useful for the initial evaluation, but they cannot reveal every detail of the packaging components.

Physical samples allow the machine manufacturer to:

• Test bottle stability on the conveyor
• Confirm filling-nozzle compatibility
• Set the required liquid level
• Manufacture the correct crimping head
• Test the crimping tightness and appearance
• Customize the collar-pressing mold
• Test outer-cap installation
• Evaluate format-change requirements
• Test the complete packaging process before shipment

The components should be sent as complete sets:

Perfume Bottle + Spray Pump + Dip Tube + Decorative Collar + Outer Cap

Sending only the bottle is not sufficient because the closing system depends on how all the components fit together.

For machine testing, the customer should normally prepare approximately 20–50 complete sets for each packaging format. The final sample quantity depends on the production-line configuration and testing requirements.

Example: Customizing the ZONESUN ZS-FAL180X11

The ZONESUN ZS-FAL180X11 perfume filling and crimping production line combines vacuum filling, spray-pump crimping, and decorative-collar pressing.

The four-head vacuum filling section is designed for low-viscosity liquids and helps maintain consistent liquid levels in perfume bottles. After filling, the spray pump is secured to the bottle by crimping. The decorative collar is then pressed into position.

According to the current configuration, the filling section operates at approximately 20–40 bottles per minute. The actual output of the complete line depends on the bottle, pump, collar, operator, and capping process.

Example Customer Requirement

A customer plans to package 50 ml and 100 ml alcohol-based perfume.

The customer provides the following information:

• Perfume viscosity below 10 cps
• Alcohol concentration of approximately 80%
• Two glass bottle formats
• Bottle and bottle-opening drawings
• 15 mm crimp spray pumps
• Pre-cut dip tubes
• Press-fit decorative collars
• Snap-on outer caps
• Required speed of 20 bottles per minute
• Manual placement of pumps, collars, and outer caps
• Bottle labeling and batch coding requirements
• 220 V, 60 Hz power supply
• Compressed air of 0.6–0.8 MPa
• Thirty complete sample sets for each format

Based on this information, ZONESUN can evaluate the vacuum filling system, conveyor guides, crimping head, collar-pressing mold, outer-cap pressing system, and labeling equipment.

If the customer later requires higher production capacity, automatic pump, collar, and cap feeding systems can also be evaluated.

Optional Equipment for a Complete Perfume Packaging Line

Depending on the production process, the ZS-FAL180X11 can be combined with additional equipment such as:

• Bottle cleaning machine
• Bottle feeding or unscrambling system
• Automatic spray-pump feeder
• Automatic decorative-collar feeder
• Outer-cap pressing machine
• Bottle labeling machine
• Batch coding machine
• Visual inspection system
• Finished-product collection table
• Cartoning machine
• Cellophane wrapping machine

The appropriate equipment should be selected according to the required process rather than adding every available machine to the line.

Conclusion

A perfume filling and crimping line should not be selected only according to bottle capacity.

The perfume viscosity, required liquid level, bottle-opening dimensions, spray pump, decorative collar, outer cap, production speed, and level of automation all affect the final machine configuration.

Complete information helps the equipment manufacturer select the appropriate filling method, manufacture suitable crimping and pressing components, plan the production-line speed, and test the complete packaging process before delivery.

To customize a perfume packaging line, provide ZONESUN with your bottle photos, dimensional drawings, packaging components, production requirements, and complete physical samples. ZONESUN can then recommend a suitable solution for bottle cleaning, vacuum filling, pump crimping, collar pressing, cap installation, labeling, coding, and final packaging.
