A automatic flow wrapping system is an automated packaging system that encloses products in 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 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 wrap products at a steady production rate.

1. Automatic 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

Cross seals are formed at each end before the package is cut from the continuous film.

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.

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.

Product Protection

The sealed film can shield products against dirt, moisture, contamination and handling damage during storage and transport.

Adaptable Product Handling

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

Common Flow Wrapping Applications

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

Common examples include:

• Individual or grouped biscuits
• Bakery products
• Chocolate and confectionery
• Fruit and vegetables
• Frozen foods
• Medical products and devices
• Pharmaceutical products
• Cosmetics and personal care items
• Household goods
• Small industrial and hardware parts

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

What Films Can a Flow Wrapping Machine Use?

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
• Polyethylene terephthalate film

Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.

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.

What Is the Difference Between Flow Wrapping and 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.

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?

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 a Flow Wrapping Machine Used For?

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 many bakery, confectionery, snack and fresh-food applications. 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.
