A flow wrapper is an automated packaging system that encloses products in flexible 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.

Flow wrappers differ from manual packaging systems because they can operate continuously. 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. Film Forming

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 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

Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.

Uniform Seals and Appearance

Each product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.

Lower Operator Requirements

Automation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.

A Protective Film Barrier

A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.

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
• 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

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

Which Packaging Films Work with Flow Wrappers?

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

Available film options include:

• BOPP film
• Polyolefin packaging film
flow wrapping machines
• 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:

• Production volumes continue to increase
• Manual packaging slows the production line
• Packaging quality varies between operators
• You need more repeatable packaging results
• Manual packaging is becoming more expensive

Automatic packaging can improve productivity while maintaining consistent pack quality.

How Do You Choose a Flow Wrapping Machine?

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

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.

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.
