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 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 production lines that require fast and consistent packaging.
How Does Flow Wrapping Machinery Work?
Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.
1. Automatic 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. Longitudinal Sealing
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. 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.
Uniform Seals and Appearance
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.
Product Protection
The sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.
Packaging for Different Products
The equipment can be configured for varied product formats and packaging materials.
Common Flow Wrapping Applications
The process can package products from several different sectors.
Typical applications include:
- Biscuits
- Cakes, bread products and other bakery goods
- Sweets, chocolate bars and confectionery
- Fresh produce
- Frozen foods
- Medical products and devices
- Pharmaceutical products
- Cosmetics and personal care items
- Household goods
- Small industrial and hardware parts
Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.
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 packaging film
- Polyethylene film
- Polyethylene terephthalate 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?
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 check here
- 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
- Printed-film registration using photocells
- Date and batch-code printing
- 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?
Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.
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
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.
