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.
The finished format is usually described as a pillow pack.
Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for production lines that require fast and consistent packaging.
How Do Flow Wrapping Machines Work?
Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.
1. Automatic Product Feeding
A conveyor or connected feeding system automatically moves products into the machine.
2. Film Forming
The machine guides the film around each product during the packaging process.
3. Longitudinal Sealing
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.
What Are the Benefits of Flow Wrapping Machines?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
Increased Production Rates
Automatic systems can package thousands of products per hour, depending on the product and machine specification.
Repeatable Pack Presentation
The machine applies consistent seals and pack formatting to every item. This can help produce a consistent presentation across a production run.
Less Manual Handling
Flow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore be assigned to other duties.
Protection During Storage and Transport
The sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.
Flexible Packaging Options
Modern machines can package many product sizes and shapes using different flexible films.
Which Products Can Flow Wrapping Machinery Package?
The process can package products from several different sectors.
Products frequently packaged in this way include:
- Biscuits
- Cakes, bread products and other bakery goods
- Chocolate 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 film
- PET film
The most suitable film depends on the product, required shelf life, desired presentation and production environment.
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
- Manual packaging slows the production line
- Packaging quality varies between operators
- Greater consistency is required
- Manual packaging is becoming more expensive
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:
- here
- Maximum production speed
- Supported product dimensions
- Fast and straightforward changeovers
- Photocell registration for printed films
- 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.
Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.
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.
