A flow wrapping machine is an automated packaging system that wraps individual products in flexible packaging film. The machine forms a seal along the length of the pack and seals at both ends 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 Does Flow Wrapping Machinery Work?
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. 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
End-sealing jaws close the package before cutting it into an individual pack.
5. Finished Product
The sealed package exits the machine and can then be stored, distributed or displayed.
Advantages of Flow Wrapping Machinery
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
Fast Packaging Output
Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.
Consistent Packaging Quality
Each product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.
Reduced Labour Costs
Automation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.
A Protective Film Barrier
Flow wrapping helps protect products from dust, moisture, contamination and physical damage during distribution and storage.
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?
Flow wrapping machinery can be used for many food and non-food products.
Typical applications include:
- Individual or grouped biscuits
- Bakery products
- 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:
- 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
- Pack appearance or seal quality is inconsistent
- Greater consistency is required flow wrap machine
- Labour costs are increasing
Automation may provide steadier production without reducing packaging consistency.
Key Flow Wrapper Features
Several factors should be considered when selecting flow wrapping machinery.
Important features include:
- Packaging speed
- Product size capacity
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- 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.
Flow wrapping machinery forms film around the product before applying length and end seals.
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 a Flow Wrapper Integrate with Existing Equipment?
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 increase packaging output without rebuilding the entire production process.
