A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms a seal along the length of the pack and seals at both ends to create a closed package.

The finished format is usually described as a pillow pack.

Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for manufacturers processing high volumes of products.

How Does Flow Wrapping Machinery Work?

A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.

1. Products Enter the Machine

A conveyor or connected feeding system automatically moves products into the machine.

2. Packaging Film Positioning

As the item travels forward, the machine forms the flexible film around it.

3. Sealing Along the Pack

The film is sealed along its length to create a continuous tube around the product.

4. Cross Sealing and Cutting

Cross seals are formed at each end before the package is cut from the continuous film.

5. Finished Product

Once sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.

Advantages of Flow Wrapping Machinery

Flow wrapping equipment can help manufacturers improve output and produce consistent packs.

Fast Packaging Output

Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.

Consistent Packaging Quality

Each product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.

Reduced Labour Costs

Automation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.

A Protective Film Barrier

Flow wrapping helps protect products from dust, moisture, contamination and physical damage during distribution and storage.

Packaging for Different Products

The equipment can be configured for varied product formats and packaging materials.

What Can Be Packaged Using a Flow Wrapper?

A flow wrapper is suitable for a wide selection of food and manufactured goods.

Common examples include:

• Individual or grouped biscuits
• Bakery products
• Sweets, chocolate bars and confectionery
• Fresh produce
• Selected frozen products
• Medical devices
• Pharmaceutical goods
• Personal care products
• Domestic and consumer products
• Hardware components

Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.

Flow Wrapping Film Options

Different film materials can be used according to the packaging requirements.

Available film options include:

• BOPP film
• Polyolefin packaging film

• Polyethylene (PE)
• PET film

The correct material will be determined by the product type, storage period, presentation requirements and production setting.

When Should You Invest in a Flow Wrapping Machine?

An automatic flow wrapper may become suitable when manual processes start slowing the production line.

You may benefit from upgrading when:

• Production volumes continue to increase
• Hand wrapping creates a production bottleneck
• Pack appearance or seal quality is inconsistent
• You need more repeatable packaging results
• Labour costs are increasing

A suitable flow wrapper can raise output and produce more uniform packaging.

How Do You Choose a Flow Wrapping Machine?

Machine selection requires an assessment of pack format, output and future demand.

Important features include:

• Maximum production speed
• Supported product dimensions
• Fast and straightforward changeovers
• Photocell registration for printed films
• Integrated date or batch coding
• Compatibility with automatic feeding systems
• Clear operator controls
• Consistent and dependable seals

The correct choice depends on your products, current production volume and future growth plans.

What Is the Difference Between Flow Wrapping and Shrink Wrapping?

Although both methods use flexible film, the packaging processes are different.

A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.

Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.

The choice will depend on the desired pack format, the product and how it will be stored or transported.

Can Flow Wrapping Machinery Be Added to an Existing Production Line?

In many cases, yes. Current flow wrappers may be installed as part of an established production system.

Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to raise production capacity without replacing every existing system.
