Flow Wrapping Machines Explained
A automatic flow wrapping system 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
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. Cross Sealing and Cutting
Cross seals are formed at each end before the package is cut from the continuous film.
5. Finished Product
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?
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
Increased Production Rates
Automatic systems can package thousands of products per hour, depending on the product and machine specification.
Repeatable Pack Presentation
Products pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.
Lower Operator Requirements
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 storage and transport.
Flexible Packaging Options
Modern machines can package many product sizes and shapes using different flexible films.
Which Products Can Flow Wrapping Machinery Package?
Flow wrapping machinery can be used for many food and non-food products.
Common examples include:
- Individual or grouped biscuits
- Cakes, bread products and other bakery goods
- Sweets, chocolate bars and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and devices
- Pharmaceutical goods
- Personal care products
- Domestic and consumer products
- Hardware components
Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.
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 film
- Polyethylene (PE) more info
- 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
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.
Important features include:
- Packaging speed
- Product size capacity
- Easy product 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.
What Is the Difference Between Flow Wrapping and Shrink Wrapping?
Both systems package products in flexible material, although their operating methods differ.
A flow wrapper creates a closed pillow-shaped pack using continuous film.
Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.
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?
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.
