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

Because of its shape, the finished package is commonly known 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 production lines that require fast and consistent packaging.

How Do Flow Wrapping Machines Work?

Flow wrapping machinery uses a continuous roll of flexible film to wrap products at a steady production rate.

1. Product Feeding

Products enter the wrapping section through an automatic conveyor or feeding arrangement.

2. The Film Is Formed Around the Product

The packaging film is shaped around each product as it moves through the machine.

3. The Length Seal Is Formed

The machine seals the film lengthways so that it surrounds the product in a tube.

4. End Sealing and Cutting

End-sealing jaws close the package before cutting it into an individual pack.

5. Finished Product

The sealed package exits the machine and can then be stored, distributed or displayed.

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.

Uniform Seals and Appearance

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

Lower Operator Requirements

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

A Protective Film Barrier

A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.

Packaging for Different Products

Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.

What Can Be Packaged Using a Flow Wrapper?

Flow wrapping machinery can be used for many food and non-food products.

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.

Common materials include:

here
• BOPP film
• Polyolefin packaging film
• Polyethylene film
• PET film

The most suitable film depends on the product, required shelf life, desired presentation and production environment.

When Is It Time to Use Flow Wrapping Machinery?

Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.

Signs that an upgrade may be needed include:

• Your required packaging output is rising
• Hand wrapping creates a production bottleneck
• Packaging quality varies between operators
• Greater consistency is required
• Labour costs are increasing

Automation may provide steadier production without reducing packaging consistency.

Key Flow Wrapper Features

Several factors should be considered when selecting flow wrapping machinery.

Specifications to review include:

• Packaging speed
• Product size capacity
• Easy product changeovers
• Printed-film registration using photocells
• Date and batch-code printing
• Automatic feeding integration
• 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?

Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.

A flow wrapper creates a closed pillow-shaped pack using continuous 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 a Flow Wrapper Integrate with Existing Equipment?

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.
