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 manufacturers processing high volumes of products.

What Is the Flow Wrapping Process?

A flow wrapping machine uses a continuous roll of flexible film to produce repeatable sealed packs.

1. Products Enter the Machine

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

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. Pack Exit

The completed pillow pack leaves the machine ready for storage, transport or retail display.

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.

Products frequently packaged in this way include:

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

Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.

Which Packaging Films Work with Flow Wrappers?

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

Frequently used films include:

• BOPP film
• Polyolefin film
• Polyethylene (PE)
• Polyethylene terephthalate 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.

Key Flow Wrapper Features

Several factors should be considered when selecting flow wrapping machinery.

Important features include:

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

Businesses should consider presentation, product characteristics and post-production handling when selecting a system.

Can a Flow Wrapper Integrate with Existing Equipment?

Yes. Many flow wrapping machines are designed to connect with existing production equipment.

Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to add automated packaging without making major changes to the full production line.

Questions About Flow Wrapping Machinery

What Is a Flow Wrapping Machine Used For?

A flow wrapping machine wraps separate products in flexible packaging film and produces closed pillow-shaped packs. These packs can protect products during storage, transport and retail display.

Is Flow Wrapping Suitable for Food Products?

Yes. Flow wrapping is widely used for many bakery, confectionery, snack and fresh-food applications. It provides closed packaging that supports hygienic handling.

Can Flow Wrapping Machinery Package Non-Food Products?

Yes. Manufacturers use flow wrapping machinery for medical items, pharmaceuticals, small components, personal care goods and household products.

How Many Products Can a Flow Wrapper Package?

Operating speed depends on the machine and the product being packaged. Many high-performance machines can package thousands of individual items each hour.
