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.

The finished format is usually described 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

A conveyor or connected feeding system automatically moves products into the machine.

2. Packaging Film Positioning

As the item travels forward, the machine forms the flexible film around it.

3. Sealing Along the Pack

A longitudinal seal joins the film beneath or above the product, forming a continuous tube.

4. The Pack Is Sealed and Separated

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

5. The Completed Pillow Pack

Once sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.

What Are the Benefits of Flow Wrapping Machines?

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

Increased Production Rates

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.

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.

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:

• Individual or grouped biscuits
• Bakery products
• Sweets, chocolate bars and confectionery
• Fresh produce
• Selected frozen products
• Medical devices
• Pharmaceutical goods
• Cosmetics and personal care items
• Domestic and consumer products
• Small industrial and hardware parts

Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.

What Films Can a Flow Wrapping Machine Use?

The correct flexible film will depend on the item being packed and the conditions it must withstand.

Common materials include:

• Biaxially oriented polypropylene film
• Polyolefin packaging film
• Polyethylene film
• Polyethylene terephthalate film

Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.

Should Your Business Move to Automatic Flow Wrapping?

Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.

A flow wrapping machine may be suitable if:

• Production volumes continue to increase
• Manual packaging slows the production line
• Pack appearance or seal quality is inconsistent
• You need more repeatable packaging results
• Manual packaging is becoming more expensive

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

• Reliable sealing performance

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

How Do Flow Wrappers Differ from Shrink Wrap Machines?

Both systems package products in flexible material, although their operating methods differ.

Flow wrapping machinery forms film around the product before applying length and end seals.

A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.

The right method depends on the required appearance, product type and handling conditions after packaging.

Can Flow Wrapping Machinery Be Added to an Existing Production Line?

In many cases, yes. Current flow wrappers may be installed as part of an established production system.

The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.

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.

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.

Can a Flow Wrapper Be Used for Manufactured Goods?

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.
