A automatic flow wrapping system 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.

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?

Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.

1. Product Feeding

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

2. The Film Is Formed Around the Product

The packaging film is shaped around each product as it moves through the machine.

3. Sealing Along the Pack

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

4. The Pack Is Sealed and Separated

End-sealing jaws close the package before cutting it into an individual pack.

5. Pack Exit

The sealed package exits the machine and can then be stored, distributed or displayed.

Advantages of Flow Wrapping Machinery

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

Products pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.

Lower Operator Requirements

Automation reduces the amount of manual handling needed during packaging. Staff can therefore spend less time on repetitive packaging work.

A Protective Film Barrier

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

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
• Small industrial and hardware parts

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:

• Biaxially oriented polypropylene 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
• Manual packaging is becoming more expensive

Automatic packaging can improve productivity while maintaining consistent pack quality.

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.

Flow wrapping machinery forms film around the product before applying length and end seals.

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 a Flow Wrapper Integrate with Existing Equipment?

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.

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.
