GREPACK has recently completed a customized automatic bottle filling, capping, and labeling system for liquid packaging applications. This system is designed for 500ml to 5000ml bottle filling requirements and integrates filling, capping, labeling, and conveying functions into one connected packaging solution.

The system is equipped with a 6-head dual-servo filling machine, 150L storage tank, bottle positioning capping device, 6-wheel cap tightening machine, double-side labeling and positioning mechanism, and conveyor systems.

This solution is suitable for round bottles and different bottle sizes within the 500ml–5000ml filling range. It can be customized according to product type, bottle size, filling volume, cap type, labeling requirements, and factory layout.

6-Head Servo Filling System for Accurate Liquid Filling

The core part of this system is the 6-head servo filling machine. Servo control helps improve filling stability and accuracy, especially for medium and large-volume liquid bottle filling applications.

The filling range of this machine is 500ml to 5000ml, making it suitable for different bottle packaging needs, including 500ml, 1L, 2L, 3L, and 5L bottles.

The filling accuracy requirement of this project is ±0.5%, helping the customer maintain consistent filling volume and reduce product waste during production.

Integrated Filling, Capping, and Labeling Process

In addition to automatic filling, the system includes bottle positioning capping and cap tightening functions. The bottle positioning capping device helps ensure stable cap placement, while the 6-wheel cap tightening system improves cap sealing consistency for bottles and wide-mouth containers.

The line also includes a double-side labeling and positioning mechanism, which is suitable for round bottles. This helps improve label position consistency and finished product appearance.

For factories that need filling, capping, and labeling in one connected workflow, this system provides a practical and efficient packaging solution.

 Suitable Applications

This automatic liquid bottle filling capping labeling line can be used for a wide range of liquid products, including:

* Liquid detergent 
* Cleaning liquid 
* Daily chemical liquid 
* Chemical liquid 
* Lubricant oil 
* Edible oil 
* Household liquid products 
* Industrial liquid products 
The machine can be customized based on product viscosity, bottle shape, filling volume, cap type, label type, and required production capacity.

Stainless Steel Structure and 316L Contact Parts

For this project, the machine structure is made of stainless steel, and the material contact parts are made of 316L stainless steel. This design is suitable for liquid packaging applications where hygiene, corrosion resistance, and stable production performance are important.

The system can also be customized for different liquid characteristics, such as corrosive liquids, foaming liquids, viscous liquids, or other special packaging requirements.

Why Choose a Customized Filling Capping Labeling Line?

A customized filling capping labeling line helps factories improve packaging efficiency, reduce manual operation, and achieve more stable production.

This type of system is especially suitable for customers who need:

* Different bottle size compatibility 
* Stable filling accuracy 
* Automatic capping 
* Consistent labeling position 
* Bottle conveying and positioning 
* Customized machine layout 
* Factory-scale liquid packaging

GREPACK can design a suitable configuration according to the customer’s product and packaging process.
