A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end seals 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.

 

 

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

 

 

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

 

 

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.

 

 

A Protective Film Barrier

 

 

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

 

 

Packaging for Different Products

 

 

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
• 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.

 

 

Which Packaging Films Work with Flow Wrappers?

 

 

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 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
• flow wrap machine
• 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
• 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. 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.

Flow Wrapping Machine FAQs

 

 

What Is the Purpose of Flow Wrapping Machinery?

 

 

A flow wrapping machine packages individual products in flexible film to form sealed pillow packs. These packs can provide protection during handling, distribution and display.

 

 

Are Flow Wrappers Used for Food Packaging?

 

 

Yes. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides a hygienic sealed pack.

 

 

Are Flow Wrappers Suitable for Non-Food Items?

 

 

Yes, they can. Manufacturers use flow wrapping machinery for pharmaceutical products, medical devices, hardware, cosmetics and consumer goods.

 

 

What Is the Speed of a Flow Wrapping Machine?

 

 

Packaging speed is affected by the equipment model, pack format and item being handled. Many high-performance machines can produce several thousand sealed packs in an hour.
