What Does a Flow Wrapping Machine Do?
A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms a longitudinal seal and two end seals to create a closed package.
Because of its shape, the finished package is commonly known as a pillow pack.
Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for businesses that need to package large quantities efficiently.
What Is the Flow Wrapping Process?
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. The Film Is Formed Around the Product
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. Cross Sealing and Cutting
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.
Advantages of Flow Wrapping Machinery
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
High Production Speeds
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Uniform Seals and Appearance
Each product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.
Reduced Labour Costs
Flow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore be assigned to other duties.
Product Protection
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?
Flow wrapping machinery can be used for many food and non-food products.
Typical applications include:
- Individual or grouped biscuits
- Bakery products
- Sweets, chocolate bars 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?
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 (PE)
- PET film
The most suitable film depends on the product, required shelf life, desired presentation and production environment.
Should Your Business Move to Automatic Flow Wrapping?
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
- Pack appearance or seal quality is inconsistent
- You need more repeatable packaging results check here
- Labour costs are increasing
Automation may provide steadier production without reducing packaging consistency.
What Features Should You Look for in Flow Wrapping Machinery?
Machine selection requires an assessment of pack format, output and future demand.
Important features include:
- Packaging speed
- Product size capacity
- Fast and straightforward changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Compatibility with automatic feeding systems
- User-friendly controls
- Consistent and dependable seals
Machine suitability will be determined by the items being packed, required output and expected business growth.
Flow Wrapping Versus Shrink Wrapping
Although both methods use flexible film, the packaging processes are different.
A flow wrapper creates a closed pillow-shaped pack using continuous film.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
Businesses should consider presentation, product characteristics and post-production handling when selecting a system.
Can a Flow Wrapper Integrate with Existing Equipment?
Yes. Flow wrapping machinery can often be integrated with equipment already in use.
Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to raise production capacity without replacing every existing system.
