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.
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 businesses that need to package large quantities efficiently.
How Does Flow Wrapping Machinery Work?
Flow wrapping machinery uses a continuous roll of flexible film to wrap products at a steady production rate.
1. 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. 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. Pack Exit
The sealed package exits the machine and can then be stored, distributed or displayed.
Advantages of Flow Wrapping Machinery
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
High Production Speeds
Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.
Uniform Seals and Appearance
Products pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.
Lower Operator Requirements
An automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.
A Protective Film Barrier
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.
Which Products Can Flow Wrapping Machinery Package?
Flow wrapping machinery can be used for many food and non-food products.
Typical applications include:
- Biscuits
- Cakes, bread products and other bakery goods
- 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.
Available film options include:
- website
- 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
- Hand wrapping creates a production bottleneck
- 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?
The correct machine should be chosen according to the product and production requirements.
Specifications to review include:
- Maximum production speed
- Product size capacity
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls
- 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?
Both systems package products in flexible material, although their operating methods differ.
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
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 creates sealed film packs around individual items. 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 secure and hygienic packaging.
Can a Flow Wrapper Be Used for Manufactured Goods?
Yes. Manufacturers use flow wrapping machinery for a range of healthcare, industrial and consumer 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.
