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?

Automatic flow wrapping equipment uses a continuous roll of flexible film to package products quickly and consistently.

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

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

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

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

The machine applies consistent seals and pack formatting to every item. This can help produce a consistent presentation across a production run.

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.

Typical applications include:

• 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

Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.

Flow Wrapping Film Options

Different film materials can be used according to the packaging requirements.

Available film options include:

• BOPP film
• Polyolefin packaging film
• Polyethylene film
• PET film

The most suitable film depends on the product, required shelf life, desired presentation and production environment.

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:

here
• Your required packaging output is rising
• Manual packaging slows the production line
• Packaging quality varies between operators
• Greater consistency is required
• Manual packaging is becoming more expensive

Automation may provide steadier production without reducing packaging consistency.

What Features Should You Look for in Flow Wrapping Machinery?

The correct machine should be chosen according to the product and production requirements.

Useful machine features include:

• Maximum production 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.

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.
