A automatic flow wrapping system is an automated packaging system that encloses products in flexible 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
A conveyor or connected feeding system automatically moves products into the machine.
2. Packaging Film Positioning
As the item travels forward, the machine forms the flexible film around it.
3. Sealing Along the Pack
The film is sealed along its length to create a continuous tube around the product.
4. The Pack Is Sealed and Separated
Cross seals are formed at each end before the package is cut from the continuous film.
5. The Completed Pillow Pack
Once sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.
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
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
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
An automated system reduces hands-on work throughout the wrapping process. 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.
What Can Be Packaged Using a Flow Wrapper?
A flow wrapper is suitable for a wide selection of food and manufactured goods.
Common examples include:
- Individual or grouped biscuits
- Bakery products
- Chocolate and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and devices
- Pharmaceutical products
- Cosmetics and personal care items
- Household goods
- Small industrial and hardware parts
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Which Packaging Films Work with Flow Wrappers?
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?
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
- Manual packaging slows the production line
- Packaging quality varies between operators
- You need more repeatable packaging results read more
- 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
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls
- Consistent and dependable seals
Machine suitability will be determined by the items being packed, required output and expected business growth.
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.
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.
Can Flow Wrapping Machinery Be Added to an Existing Production Line?
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.
