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.
Because of its shape, the finished package is commonly known as a pillow pack.
Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for businesses that need to package large quantities efficiently.
What Is the Flow Wrapping Process?
Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.
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. The Length Seal Is Formed
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?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
Increased Production Rates
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Repeatable Pack Presentation
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.
Flexible Packaging Options
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
- 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.
Common materials include:
- BOPP film
- Polyolefin packaging film
- Polyethylene (PE)
- PET film
The correct material will be determined by the product type, storage period, presentation requirements and production setting.
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
- 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.
Important features include:
- Packaging speed
- Product size capacity
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls check here
- Reliable sealing performance
Machine suitability will be determined by the items being packed, required output and expected business growth.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.
Flow wrapping machinery forms film around the product before applying length and end seals.
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.
Flow Wrapping Machine Integration
In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.
The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.
