A automatic flow wrapping system is an automated packaging system that wraps individual products in flexible packaging film. The machine forms long seals and cross seals 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 are carried into the machine by a conveyor or integrated feeding system.
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. End Sealing and Cutting
The machine creates end seals and then separates each pack from the film web.
5. Finished Product
Once sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.
What Are the Benefits of Flow Wrapping Machines?
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
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.
Protection During Storage and Transport
The sealed film can shield products against dirt, moisture, contamination and handling damage during storage and transport.
Flexible Packaging Options
Modern machines can package many product sizes and shapes using different flexible films.
Common Flow Wrapping Applications
The process can package products from several different sectors.
Typical applications include:
- Individual or grouped biscuits
- Bakery products
- Chocolate and confectionery
- Fruit and vegetables
- Selected frozen products
- Medical devices
- Pharmaceutical goods
- Personal care products
- Domestic and consumer products
- Hardware components
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?
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Available film options include:
- BOPP film
- Polyolefin 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?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
You may benefit from upgrading when:
- Production volumes continue to increase
- Hand wrapping creates a production bottleneck
- Packaging quality varies between operators
- Greater consistency is required
- Manual packaging is becoming more expensive
A suitable flow wrapper can raise output and produce more uniform packaging.
Key Flow Wrapper Features
The correct machine should be chosen according to the product and production requirements.
Useful machine features include:
- Maximum production speed
- Supported product dimensions
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Compatibility with automatic feeding systems
- Clear operator controls here
- Consistent and dependable seals
The correct choice depends on your products, current production volume and future growth plans.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
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.
With shrink wrapping, the product is enclosed in film that shrinks when it passes through a heat tunnel.
The right method depends on the required appearance, product type and handling conditions after packaging.
Can Flow Wrapping Machinery Be Added to an Existing Production Line?
Yes. Many flow wrapping machines are designed to connect with existing production equipment.
Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to add automated packaging without making major changes to the full production line.

Questions About Flow Wrapping Machinery
What Is a Flow Wrapping Machine Used For?
A flow wrapping machine creates sealed film packs around individual items. These packs can help shield items while they are stored, delivered or presented for sale.
Are Flow Wrappers Used for Food Packaging?
Yes, they are. 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.
