A automatic flow wrapping system 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.

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. 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. Pack Exit

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

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

Flow wrapping machinery limits the need for employees to wrap every product by hand. 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 goods
• Personal care products
• Household goods
• 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
• Polyolefin packaging film
• Polyethylene (PE)
• PET film

The correct material will be determined by the product type, storage period, presentation requirements and production setting.

When Is It Time to Use Flow Wrapping Machinery?

Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.

Signs that an upgrade may be needed include:

• Your required packaging output is rising
• Hand wrapping creates a production bottleneck
• 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:

• Maximum production speed
• Supported product dimensions
• Fast and straightforward changeovers
• Photocell registration for printed films
• Integrated date or batch coding
• 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.

Flow Wrapping Versus Shrink Wrapping

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 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.
