A flow wrapping machine is an automated packaging system that wraps individual products in flexible packaging film. The machine forms long seals and cross seals 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 production lines that require fast and consistent packaging.

How Do Flow Wrapping Machines Work?

Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.

1. Automatic Product Feeding

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

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

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

Fast Packaging Output

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 maintain a uniform brand appearance.

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
• Fruit and vegetables
• 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
flow wrapping machinery
• 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
• Hand wrapping creates a production bottleneck
• Pack appearance or seal quality is inconsistent
• You need more repeatable packaging results
• Labour costs are increasing

A suitable flow wrapper can raise output and produce more uniform packaging.

How Do You Choose a Flow Wrapping Machine?

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

Important features include:

• Packaging speed
• Supported product dimensions
• Easy product changeovers
• Photocell registration for printed films
• Integrated date or batch coding
• Compatibility with automatic feeding systems
• Clear operator controls
• Consistent and dependable seals

Your product range, packaging volume and projected demand should guide the final machine specification.

Flow Wrapping Versus Shrink Wrapping

Although both methods use flexible film, the packaging processes are different.

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

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 help shield items while they are stored, delivered or presented for sale.

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.
