A flow wrapping machine is an automated packaging system that wraps individual products in flexible packaging 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

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

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.

Less Manual Handling

An automated system reduces hands-on work throughout the wrapping process. Staff can therefore be assigned to other duties.

Protection During Storage and Transport

The sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.

Flexible Packaging Options

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.

Products frequently packaged in this way include:

• Biscuits
• Cakes, bread products and other bakery goods
• Chocolate and confectionery
• Fruit and vegetables
• Frozen foods
• Medical products and devices
• Pharmaceutical products
• Cosmetics and personal care items
• Household goods
• Small industrial and hardware parts

Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.

What Films Can a Flow Wrapping Machine Use?

A flow wrapping machine can use several flexible packaging films depending on the product and application.

Frequently used films include:

• Biaxially oriented polypropylene film
• Polyolefin film
• Polyethylene (PE)
• Polyethylene terephthalate film

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

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.

Key Flow Wrapper Features

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

Important features include:

• Packaging speed
• Supported product dimensions
• Fast and straightforward 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.

What Is the Difference Between Flow Wrapping and 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 a Flow Wrapper Integrate with Existing Equipment?

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 wraps separate products in flexible packaging film and produces closed pillow-shaped packs. These packs can provide protection during handling, distribution and display.

Is Flow Wrapping Suitable for Food Products?

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

Can Flow Wrapping Machinery Package Non-Food Products?

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

How Many Products Can a Flow Wrapper Package?

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