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

Cross seals are formed at each end before the package is cut from the continuous film.

5. The Completed Pillow Pack

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

Why Use a Flow Wrapping Machine?

Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.

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.

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

Flow wrapping helps protect products from dust, moisture, contamination and physical damage during storage and transport.

Adaptable Product Handling

Modern machines can package many product sizes and shapes using different flexible films.

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 products and devices
• Pharmaceutical products
• 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)
• 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
• 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.

How Do Flow Wrappers Differ from Shrink Wrap Machines?

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.

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

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

Flow Wrapping Machine Integration

Yes. Flow wrapping machinery can often be integrated with equipment already in use.

Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to increase packaging output without rebuilding the entire production process.

Questions About Flow Wrapping Machinery

What Is a Flow Wrapping Machine Used For?

A flow wrapping machine creates sealed film packs around individual items. These packs can protect products during storage, transport and retail display.

Can Food Be Packaged with a Flow Wrapper?

Yes, they are. Flow wrapping is widely used for bakery goods, confectionery, snacks and fresh 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.
