A flow wrapper 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 finished format is usually described 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. 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.
Why Use a Flow Wrapping Machine?
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
High Production Speeds
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 maintain a uniform brand appearance.
Lower Operator Requirements
Automation reduces the amount of manual handling needed during packaging. 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 distribution and storage.
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
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Which Packaging Films Work with Flow Wrappers?
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Frequently used films include:
- BOPP film
- Polyolefin film
- Polyethylene (PE)
- Polyethylene terephthalate film
Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.
When Should You Invest in a Flow Wrapping Machine?
An automatic flow wrapper may become suitable when manual processes start slowing the production line.
You may benefit from upgrading when:
- Production volumes continue to increase
- Manual packaging slows the production line
- Pack appearance or seal quality is inconsistent
- You need more repeatable packaging results
- Manual packaging is becoming more expensive
Automatic packaging can improve productivity while maintaining consistent pack quality.
How Do You Choose a Flow Wrapping Machine?
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
- Printed-film registration using photocells read more
- 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.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
Both systems package products in flexible material, although their operating methods differ.
A flow wrapping machine forms a sealed pillow pack from a continuous roll of 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
In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.
The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.
