Across many industries, including food and beverage, cosmetics, e-liquids, chemicals, essential oils, paints and healthcare products, manufacturers are facing a simple reality: product ranges are becoming increasingly diverse. A single company may market the same product in different volumes, offer several bottle designs, alternate between standard caps, pipettes, pumps and screw caps, or use different packaging depending on the distribution channel. As a result, multi-format packaging has become a key consideration.

When a single production line has to handle multiple formats, several factors must be taken into account: ease of adjustment, container compatibility, changeover management, production scalability, machine footprint, level of automation and overall finishing quality. Should you invest in a standalone filler? Add a capper? Integrate a labeller? Or would it be more efficient to choose a packaging monobloc capable of combining filling, capping and labelling within a single machine?

The answer depends on your business, production volumes, products and overall manufacturing strategy. One thing is certain: when a packaging line needs to process multiple product references, the versatility of the packaging machine becomes just as important for productivity as its output speed.

Below are the key criteria to consider when selecting the right machine for packaging multiple formats on a single production line, along with the principles for designing a packaging line that remains efficient despite handling a wide variety of containers.

 

Why Has Multi-Format Packaging Become Such an Important Challenge?

Brands are expanding their product portfolios, launching more product variants, adapting pack sizes to new consumer needs and targeting increasingly segmented markets.

In practical terms, this means that a single production line may need to handle:

  • small bottles as well as larger containers;
  • cylindrical, oval and conical containers, as well as more specialised shapes;
  • various types of caps and closures;
  • products with different viscosities;
  • multiple labelling stations depending on packaging requirements;
  • both long production runs and shorter manufacturing batches.

In this context, a production line designed for a single format quickly becomes a limitation. By contrast, a multi-format packaging line enables manufacturers to:

  • reduce the number of dedicated machines required;
  • optimise production floor space;
  • introduce new product references more easily;
  • control manufacturing costs;
  • improve responsiveness to market demand.

This is precisely where versatile packaging equipment comes into its own. Fillers, cappers, labellers and, above all, packaging monoblocs are designed to switch from one container format to another with minimal adjustments while maintaining maximum reliability.

 

Packaging Multiple Formats on the Same Production Line: The Key Questions to Ask

Before choosing a machine, you first need to identify the actual constraints of your packaging line.

1. Which Containers Do You Need to Package?

The first consideration is the variety of container formats. Make a precise list of:

  • the fill volumes to be processed (5 ml, 10 ml, 30 ml, 250 ml, 1 L, etc.);
  • container diameters and heights;
  • container materials (glass, PET, HDPE, metal, etc.);
  • container shapes (cylindrical, square, conical, oval, dropper bottles, jerrycans, jars, etc.).

A genuinely multi-format machine must be able to accommodate this diversity through simple, fast and reliable changeovers. The greater the differences between container formats, the more carefully the packaging line should be designed.

2. What Type of Product Are You Packaging?

The choice of a filling machine depends largely on the characteristics of the product being filled:

  • free-flowing liquids;
  • viscous products;
  • pastes;
  • foaming products;
  • sensitive or fragile products;
  • products requiring extremely accurate dosing.

The way a product behaves during filling determines the most appropriate filling technology. An efficient packaging machine should therefore not only be compatible with multiple container formats, but also with the viscosity and characteristics of the product itself.

3. How Often Do You Change Formats?

This is a crucial consideration. A manufacturer changing formats once a week has very different requirements from a production facility switching between several product references every day.

The more frequent the format changes, the more important it becomes to choose equipment offering:

  • intuitive machine adjustments;
  • stored production recipes;
  • minimal tooling changes;
  • a user-friendly operator interface;
  • a production line designed for maximum flexibility.

4. What Production Speed Do You Require?

Multi-format capability should never come at the expense of performance. A machine must be able to maintain the required production rate, even when processing a wide range of product references.

Depending on your requirements, you may opt for:

  • a semi-automatic machine for small and medium-sized production runs;
  • a fully automatic machine for higher production speeds;
  • a monobloc to combine several packaging operations without multiplying individual workstations.

5. Do You Need a Standalone Machine or a Complete Packaging Line?

Finally, you should determine your investment strategy.

Will you build your line progressively by installing a filler first, followed by a capper and then a labeller? Or would you rather integrate several operations into a single monobloc machine?

This question is fundamental when your objective is to package multiple formats on the same production line without increasing production complexity.

Filler, Capper or Labeller: Should You Combine Separate Machines?

In many cases, building a packaging line using separate pieces of equipment is entirely appropriate. This is often the preferred option when production requirements are highly specific or when the company intends to expand its line step by step.

The Filling Machine: The Heart of the Packaging Line

The filling machine is naturally the starting point of any packaging line. It ensures dosing accuracy, production consistency and compatibility with the product being filled.

On a multi-format line, the filler should provide:

  • highly accurate dosing;
  • the ability to process multiple fill volumes;
  • fast format adjustments;
  • excellent compatibility with different containers;
  • a design capable of meeting your required production speeds.

A semi-automatic filler may be perfectly suited to small production runs or new product launches, whereas a fully automatic filling machine is generally better suited to higher production rates and frequent format changes.

The Capper: Ensuring Reliable Closure Across Different Closures

When several container formats are processed on the same line, it is common for multiple closure types to be used as well. Screw caps, closures, pipettes, pumps and spray heads all require a capping machine capable of adapting to these variations without compromising either production speed or closure quality.

Within a multi-format production environment, an efficient capper should offer:

  • precise torque adjustment;
  • compatibility with different cap heights and diameters;
  • consistent and repeatable capping quality;
  • seamless integration with the existing production line.

On a modular packaging line, the capper complements the filling machine by securing the closure stage, a critical step for both product quality and safe transportation.

The Labeller: Delivering a High-Quality Finish Regardless of Format

Multi-format production also affects product presentation. Changing bottle formats often means changing label heights, application positions or even the number of labels required.

A labelling machine designed for multiple formats should therefore provide:

  • accurate and repeatable adjustments;
  • excellent label placement consistency;
  • compatibility with a wide range of containers;
  • effective synchronisation with the overall production speed.

On a multi-format packaging line, labelling is far from a secondary operation. It directly influences product appearance, the readability of mandatory information and the overall perception of quality.

Is a Monobloc the Best Solution for a Multi-Format Packaging Line?

When the objective is to package multiple formats on a single production line while maintaining a compact, efficient and easy-to-operate system, a monobloc often proves to be the most suitable solution.

What Is a Packaging Monobloc?

A monobloc is a machine that combines several packaging functions within a single frame, typically:

  • filling;
  • capping;
  • labelling.

Instead of installing three separate machines, manufacturers benefit from an all-in-one solution designed to ensure a continuous production process with a unified approach to machine settings, operation and container handling.

At CDA, monobloc machines are designed to combine filling, capping and labelling within a single system, making them particularly well suited to multi-format production environments.

Why Is a Monobloc Particularly Well Suited to Multi-Format Production?

The main advantage of a monobloc lies in its ability to centralise several packaging operations while minimising the interfaces between individual machines. This offers several practical benefits.

1. A More Compact Production Line

Where factory floor space is limited, combining filling, capping and labelling within a single unit provides a significant advantage. A monobloc eliminates the need for multiple conveyors, transfer sections and separate workstations.

2. Greater Consistency During Format Changeovers

When several formats must be processed, each standalone machine requires its own adjustments. With a monobloc, machine settings are integrated, making format changeovers faster, simpler and more consistent.

3. Reduced Product Handling

The fewer transfers between machines, the smoother the production flow. This is particularly beneficial when handling small containers, technical bottles or sensitive products.

4. Higher Levels of Automation

A monobloc brings packaging operations closer together and reduces manual intervention. From an industrial performance perspective, this helps maintain production speeds while improving process consistency.

5. An Ideal Solution for Diverse Product Ranges

For manufacturers producing multiple product references, often in small or medium-sized batches, a multi-format monobloc offers an excellent balance between flexibility and productivity.

CDA offers several solutions specifically designed for this type of multi-format packaging application. This is particularly evident in its range of packaging monoblocs, which integrate several packaging operations into a single machine.

E-Fill SW: A Monobloc Designed for Multi-Format Production

Among CDA’s packaging solutions, the E-Fill SW occupies a strategic position for manufacturers handling products in a wide variety of formats.

The machine combines:

  • filling;
  • cap dispensing and placement (depending on the selected configuration);
  • capping;
  • automatic labelling.

All of these operations are integrated into a single machine.

According to CDA, the E-Fill SW is designed for packaging liquid and viscous products in bottles ranging from 5 ml to 250 ml (subject to project validation and production requirements). The machine also stands out thanks to its hybrid operating concept, offering both fully automatic operation and a semi-automatic switch mode to adapt to different production needs.

 

Monoblocs Designed to Integrate Multiple Technologies

The value of a monobloc lies not only in combining several functions within a single machine. It also stems from its ability to integrate filling and capping technologies that are tailored to the specific requirements of each project.

In other words, a high-performance multi-format packaging line is not simply a standard machine installed in a production facility. It is a solution designed around:

  • the containers;
  • the closures;
  • the product itself;
  • the required production speed;
  • the frequency of format changeovers;
  • available floor space and layout constraints.

This tailored approach is essential for manufacturers whose packaging lines need to evolve over time, accommodate new product references or support the expansion of their product range.

The Importance of Complementary Equipment: The Multi-Format Bottle Unscrambler

When packaging multiple formats on the same production line, it is important to look beyond the main machine. Complementary equipment also plays a key role in ensuring a smooth and efficient production process.

For example, CDA offers an automatic multi-format bottle unscrambler designed to feed monobloc machines. This type of equipment automates the infeed of containers upstream of the production line, further increasing productivity when processing multiple product references. CDA’s solution is designed to accommodate various bottle formats, with tooling changes depending on the container sizes being handled.

When Is a Modular Packaging Line the Right Choice?

A production line made up of separate filling, capping and labelling machines may be the best solution if:

  • you wish to invest progressively;
  • your packaging operations are highly specialised;
  • certain stations need to evolve independently;
  • your containers vary significantly in shape or size;
  • you already own part of the required equipment.

When Is a Monobloc the Better Option?

A monobloc is often the preferred solution if:

  • you require a compact machine;
  • format changeovers are frequent;
  • you want to automate several packaging operations within a single production line;
  • you are looking for a system that is straightforward to operate;
  • you package small and medium-sized containers while requiring a high degree of versatility;
  • you want greater consistency between filling, capping and labelling operations.

Conclusion

Successfully packaging multiple formats on the same production line starts with choosing a solution that is versatile, scalable and suited to your actual production requirements.

In some cases, a modular packaging line made up of separate filling, capping and labelling machines will be the most appropriate choice.

In others, a monobloc will provide the highest level of performance thanks to its compact footprint, integrated control system and ability to combine several packaging operations within a single machine.

The right solution will always depend on your product, containers, closures, required production speed and the frequency of format changes. One thing is certain: in an environment where product ranges continue to expand and flexibility has become a genuine competitive advantage, a multi-format packaging machine is no longer simply a convenience—it is a strategic asset for improving industrial performance.

CDA’s range of filling machines, cappers, labellers, monoblocs and complementary equipment has been developed specifically to address these challenges, enabling manufacturers to build packaging lines that meet today’s industrial realities: more formats, more product references, higher expectations and greater productivity.
