What Does a Flow Wrapping Machine Do?

A automatic flow wrapping system is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end seals to create a closed package.

The completed package is often called a pillow pack because of its shape.

Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for businesses that need to package large quantities efficiently.

How Do Flow Wrapping Machines Work?

Flow wrapping machinery uses a continuous roll of flexible film to wrap products at a steady production rate.

1. Product Feeding

Products enter the wrapping section through an automatic conveyor or feeding arrangement.

2. Film Forming

The machine guides the film around each product during the packaging process.

3. Longitudinal Sealing

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

4. The Pack Is Sealed and Separated

The machine creates end seals and then separates each pack from the film web.

5. The Completed Pillow Pack

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

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

Automatic systems can package thousands of products per hour, depending on the product and machine specification.

Consistent Packaging Quality

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

Reduced Labour Costs

Flow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore focus on other production tasks.

Product Protection

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

Adaptable Product Handling

The equipment can be configured for varied product formats and packaging materials.

What Can Be Packaged Using a Flow Wrapper?

A flow wrapper is suitable for a wide selection of food and manufactured goods.

Common examples include:

• Individual or grouped 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

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

Flow Wrapping Film Options

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

Common materials include:

flow wrapping machinery
• 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.

When Is It Time to Use Flow Wrapping Machinery?

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

A flow wrapping machine may be suitable if:

• Your required packaging output is rising
• Manual packaging slows the production line
• Packaging quality varies between operators
• Greater consistency is required
• Labour costs are increasing

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.

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
• Reliable sealing performance

The correct choice depends on your products, current production volume and future growth plans.

What Is the Difference Between Flow Wrapping and Shrink Wrapping?

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.

Can a Flow Wrapper Integrate with Existing Equipment?

Yes. Many flow wrapping machines are designed to connect with existing production equipment.

Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to add automated packaging without making major changes to the full production line.
