A automatic flow wrapping system 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.

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 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

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.

Consistent Packaging Quality

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

Reduced Labour Costs

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.

Typical applications 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

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.

Available film options 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
• Manual packaging slows the production line
• Packaging quality varies between operators

• You need more repeatable packaging results
• Labour costs are increasing

Automation may provide steadier production without reducing packaging consistency.

How Do You Choose a Flow Wrapping Machine?

Several factors should be considered when selecting flow wrapping machinery.

Useful machine features include:

• Maximum production speed
• Supported product dimensions
• Fast and straightforward changeovers
• Printed-film registration using photocells
• Date and batch-code printing
• Automatic feeding integration
• Clear operator controls
• Consistent and dependable seals

Machine suitability will be determined by the items being packed, required output and expected business growth.

Flow Wrapping Versus Shrink Wrapping

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

A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.

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

The choice will depend on the desired pack format, the product and how it will be stored or transported.

Flow Wrapping Machine Integration

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 increase packaging output without rebuilding the entire production process.

Questions About Flow Wrapping Machinery

What Does a Flow Wrapper Package?

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.

Can Food Be Packaged with a Flow Wrapper?

Yes, they are. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides closed packaging that supports hygienic handling.

Can a Flow Wrapper Be Used for Manufactured Goods?

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

What Is the Speed of a Flow Wrapping Machine?

Operating speed depends on the machine and the product being packaged. Many high-performance machines can wrap several thousand products per hour.
