A flow wrapping machine 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.
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 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 produce repeatable sealed packs.
1. Products Enter the Machine
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
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 completed pillow pack leaves the machine ready for storage, transport or retail display.
Advantages of Flow Wrapping Machinery
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
Fast Packaging Output
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Repeatable Pack Presentation
Products pass through the same controlled sealing process. This can help maintain a uniform brand appearance.
Reduced Labour Costs
An automated system reduces hands-on work throughout the wrapping process. Staff can therefore focus on other production tasks.
Product Protection
A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.
Flexible Packaging Options
Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.
Common Flow Wrapping Applications
Flow wrapping machinery can be used for many food and non-food products.
Typical applications 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
- Small industrial and hardware parts
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Flow Wrapping Film Options
The correct flexible film will depend on the item being packed and the conditions it must withstand.
Frequently used films include:
- BOPP film
- Polyolefin packaging film get more info
- 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?
An automatic flow wrapper may become suitable when manual processes start slowing the production line.
You may benefit from upgrading when:
- Your required packaging output is rising
- Manual packaging slows the production line
- Packaging quality varies between operators
- You need more repeatable packaging results
- 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.
Important features include:
- Packaging speed
- Supported product dimensions
- Fast and straightforward changeovers
- Photocell registration for printed films
- Date and batch-code printing
- Automatic feeding integration
- Clear operator 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
Both systems package products in flexible material, although their operating methods differ.
A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
The choice will depend on the desired pack format, the product and how it will be stored or transported.
Flow Wrapping Machine Integration
In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.
Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to add automated packaging without making major changes to the full production line.

Flow Wrapping Machine FAQs
What Is the Purpose of Flow Wrapping Machinery?
A flow wrapping machine wraps separate products in flexible packaging film and produces closed pillow-shaped packs. These packs can provide protection during handling, distribution and display.
Can Food Be Packaged with a Flow Wrapper?
Yes, they are. Flow wrapping is widely used for bakery goods, confectionery, snacks and fresh produce. It provides a hygienic sealed pack.
Are Flow Wrappers Suitable for Non-Food Items?
Yes. Manufacturers use flow wrapping machinery for medical items, pharmaceuticals, small components, personal care goods and household products.
How Fast Can Flow Wrapping Machines Operate?
Packaging speed is affected by the equipment model, pack format and item being handled. Many high-performance machines can wrap several thousand products per hour.
