A flow wrapping machine 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

Products are carried into the machine by a conveyor or integrated feeding system.

2. Packaging Film Positioning

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

3. The Length Seal Is Formed

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

4. Cross 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

Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.

High Production Speeds

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

Uniform Seals and Appearance

Products pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.

Lower Operator Requirements

An automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.

Protection During Storage and Transport

A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during warehousing, handling and delivery.

Flexible Packaging Options

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

Which Products Can Flow Wrapping Machinery Package?

The process can package products from several different sectors.

Typical applications include:

• Biscuits
• Cakes, bread products and other bakery goods
• Chocolate and confectionery
• Fruit and vegetables
• Frozen foods
• Medical devices
• Pharmaceutical products
• Cosmetics and personal care items
• Household goods
• Small industrial and hardware parts

Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.

What Films Can a Flow Wrapping Machine Use?

A flow wrapping machine can use several flexible packaging films depending on the product and application.

Available film options include:

• BOPP film
• Polyolefin packaging film
• Polyethylene (PE)
• 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?

Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.

A flow wrapping machine may be suitable if:

• Your required packaging output is rising
• Manual packaging slows the production line
• Packaging quality varies between operators
• Greater consistency is required
flow wrapping machines
• Manual packaging is becoming more expensive

Automatic packaging can improve productivity while maintaining consistent pack quality.

How Do You Choose a Flow Wrapping Machine?

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

Useful machine 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?

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

Flow wrapping machinery forms film around the product before applying length and end seals.

With shrink wrapping, the product is enclosed in film that shrinks when it passes through a heat tunnel.

The right method depends on the required appearance, product type and handling conditions after packaging.

Flow Wrapping Machine Integration

In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.

The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.
