A flow wrapping machine 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 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 businesses that need to package large quantities efficiently.
What Is the Flow Wrapping Process?
A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.
1. Products Enter the Machine
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
End-sealing jaws close the package before cutting it into an individual pack.
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?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
Increased Production Rates
Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.
Uniform Seals and Appearance
Each product receives the same seal quality and presentation. This can help produce a consistent presentation across a production run.
Less Manual Handling
Automation reduces the amount of manual handling needed during packaging. 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 warehousing, handling and delivery.
Packaging for Different Products
Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.
What Can Be Packaged Using a Flow Wrapper?
The process can package products from several different sectors.
Typical applications include:
- Individual or grouped biscuits
- Cakes, bread products and other bakery goods
- Chocolate and confectionery
- Fresh produce
- 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.
Flow Wrapping Film Options
The correct flexible film will depend on the item being packed and the conditions it must withstand.
Available film options include:
- BOPP film
- Polyolefin packaging film
- Polyethylene film
- Polyethylene terephthalate 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?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
You may benefit from upgrading when:
- check here
- Your required packaging output is rising
- Manual packaging slows the production line
- Packaging quality varies between operators
- 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?
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
The correct choice depends on your products, current production volume and future growth plans.
What Is the Difference Between Flow Wrapping and Shrink Wrapping?
Although both methods use flexible film, the packaging processes are different.
A flow wrapper creates a closed pillow-shaped pack using continuous film.
Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.
Businesses should consider presentation, product characteristics and post-production handling when selecting a system.
Flow Wrapping Machine Integration
Yes. Flow wrapping machinery can often be integrated with equipment already in use.
Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to increase packaging output without rebuilding the entire production process.

Questions About Flow Wrapping Machinery
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. Flow wrapping is widely used for many bakery, confectionery, snack and fresh-food applications. It provides secure and hygienic packaging.
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.
