A flow wrapper 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.

Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for businesses that need to package large quantities efficiently.

How Do Flow Wrapping Machines Work?

Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.

1. Product Feeding

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

Why Use a Flow Wrapping Machine?

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

High Production Speeds

Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.

Repeatable Pack Presentation

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

Less Manual Handling

An automated system reduces hands-on work throughout the wrapping process. Staff can therefore be assigned to other duties.

Protection During Storage and Transport

The sealed film can shield products against dirt, moisture, contamination and handling damage 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?

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

Typical applications 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:

• Biaxially oriented polypropylene film
• Polyolefin 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?

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
• Manual packaging is becoming more expensive

Automatic packaging can improve productivity while maintaining consistent pack quality.

What Features Should You Look for in Flow Wrapping Machinery?

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

Useful machine features include:

• Maximum production 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. 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.
