A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms long seals and cross seals to create a closed package.

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

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 wrap products at a steady production rate.

1. Product Feeding

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

2. The Film Is Formed Around the Product

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

3. Longitudinal Sealing

The machine seals the film lengthways so that it surrounds the product in a tube.

4. End Sealing and Cutting

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.

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.

Lower Operator Requirements

An automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.

Protection During Storage and Transport

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
• 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 (PE)
• 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?

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
• 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.

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.

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

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.

The machine can work alongside feeding units, conveyor systems and labelling equipment. 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 package thousands of individual items each hour.
