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 manufacturers processing high volumes of products.
What Is the Flow Wrapping Process?
A flow wrapping machine 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. The Film Is Formed Around the Product
The machine guides the film around each product during the packaging process.
3. Longitudinal Sealing
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?
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
Increased Production Rates
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Repeatable Pack Presentation
Products pass through the same controlled sealing process. 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
Flow wrapping helps protect products from dust, moisture, contamination and physical damage during warehousing, handling and delivery.
Flexible Packaging Options
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.
Products frequently packaged in this way include:
- Individual or grouped biscuits
- Bakery products
- Chocolate and confectionery
- Fruit and vegetables
- Selected frozen products
- Medical devices
- Pharmaceutical products
- Cosmetics and personal care items
- Domestic and consumer products
- Hardware components
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Flow Wrapping Film Options
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Common materials include:
- BOPP film
- Polyolefin 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?
An automatic flow wrapper may become suitable when manual processes start slowing the production line.
You may benefit from upgrading when:
- Your required packaging output is rising
- 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
- Supported product dimensions
- Fast and straightforward changeovers
- Photocell registration for printed films get more info
- Integrated date or batch coding
- Compatibility with automatic feeding systems
- Clear operator controls
- Consistent and dependable seals
Your product range, packaging volume and projected demand should guide the final machine specification.
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.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
The choice will depend on the desired pack format, the product and how it will be stored or transported.
Can Flow Wrapping Machinery Be Added to an Existing Production Line?
In many cases, yes. Current flow wrappers may be installed as part of an established production system.
Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to raise production capacity without replacing every existing system.
