A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms long seals and cross seals to create a closed package.
Because of its shape, the finished package is commonly known as a pillow pack.
Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for manufacturers processing high volumes of products.
How Do Flow Wrapping Machines Work?
Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.
1. Products Enter the Machine
Products are carried into the machine by a conveyor or integrated feeding system.
2. Packaging Film Positioning
The packaging film is shaped around each product as it moves through the machine.
3. The Length Seal Is Formed
The film is sealed along its length to create a continuous tube around the product.
4. Cross Sealing and Cutting
Cross seals are formed at each end before the package is cut from the continuous film.
5. Finished Product
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.
High Production Speeds
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Uniform Seals and Appearance
Each product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.
Reduced Labour Costs
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
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.
Common Flow Wrapping Applications
The process can package products from several different sectors.
Typical applications include:
- Individual or grouped biscuits
- Bakery products
- Sweets, chocolate bars and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and devices
- Pharmaceutical products
- Cosmetics and personal care items
- 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.
Frequently used films include:
- BOPP film
- Polyolefin film check here
- Polyethylene (PE)
- 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?
An automatic flow wrapper may become suitable when manual processes start slowing the production line.
You may benefit from upgrading when:
- Production volumes continue to increase
- Hand wrapping creates a production bottleneck
- Pack appearance or seal quality is inconsistent
- Greater consistency is required
- Labour costs are increasing
Automation may provide steadier production without reducing packaging consistency.
What Features Should You Look for in Flow Wrapping Machinery?
The correct machine should be chosen according to the product and production requirements.
Specifications to review include:
- Maximum production speed
- Supported product dimensions
- Fast and straightforward changeovers
- Printed-film registration using photocells
- Integrated date or batch coding
- Compatibility with automatic feeding systems
- Clear operator controls
- 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 wrapper creates a closed pillow-shaped pack using continuous 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?
In many cases, yes. Many flow wrapping machines are designed to connect with existing production equipment.
The machine can work alongside feeding units, conveyor systems and labelling equipment. 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 protect products during storage, transport and retail display.
Can Food Be Packaged with a Flow Wrapper?
Yes, they are. Flow wrapping is widely used for bakery goods, confectionery, snacks and fresh produce. It provides a hygienic sealed pack.
Can Flow Wrapping Machinery Package Non-Food Products?
Yes. Manufacturers use flow wrapping machinery for pharmaceutical products, medical devices, hardware, cosmetics and consumer goods.
How Fast Can Flow Wrapping Machines Operate?
Packaging speed is affected by the equipment model, pack format and item being handled. Many high-performance machines can produce several thousand sealed packs in an hour.
