Flow Wrapping Machines Explained
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.
Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for production lines that require fast and consistent packaging.
How Do Flow Wrapping Machines Work?
Flow wrapping machinery 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. Packaging Film Positioning
As the item travels forward, the machine forms the flexible film around it.
3. Sealing Along the Pack
A longitudinal seal joins the film beneath or above the product, forming a continuous tube.
4. The Pack Is Sealed and Separated
The machine creates end seals and then separates each pack from the film web.
5. The Completed Pillow Pack
The completed pillow pack leaves the machine ready for storage, transport or retail display.
Why Use a Flow Wrapping Machine?
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
Fast Packaging Output
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 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.
Product Protection
Flow wrapping helps protect products from dust, moisture, contamination and physical damage during storage and transport.
Flexible Packaging Options
Modern machines can package many product sizes and shapes using different flexible films.
Which Products Can Flow Wrapping Machinery Package?
Flow wrapping machinery can be used for many food and non-food products.
Common examples include:
- Individual or grouped biscuits
- Bakery products
- Chocolate and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and 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 click 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?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
A flow wrapping machine may be suitable if:
- 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.
Useful machine features include:
- Maximum production speed
- Product size capacity
- Easy product changeovers
- Photocell registration for printed films
- Integrated date or batch coding
- Compatibility with automatic feeding systems
- User-friendly controls
- Consistent and dependable seals
Machine suitability will be determined by the items being packed, required output and expected business growth.
Flow Wrapping Versus Shrink Wrapping
Although both methods use flexible film, the packaging processes are different.
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?
In many cases, 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 increase packaging output without rebuilding the entire production process.
