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.
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?
Automatic flow wrapping equipment uses a continuous roll of flexible film to package products quickly and consistently.
1. Automatic Product Feeding
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
A longitudinal seal joins the film beneath or above the product, forming a continuous tube.
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?
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
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 spend less time on repetitive packaging work.
Protection During Storage and Transport
A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during warehousing, handling and delivery.
Packaging for Different Products
Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.
Which Products Can Flow Wrapping Machinery Package?
Flow wrapping machinery can be used for many food and non-food products.
Typical applications include:
- Biscuits
- Bakery products
- Sweets, chocolate bars and confectionery
- Fresh produce
- Selected frozen products
- Medical 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.
Flow Wrapping Film Options
The correct flexible film will depend on the item being packed and the conditions it must withstand.
Common materials include:
- Biaxially oriented polypropylene film
- Polyolefin packaging film
- Polyethylene film
- Polyethylene terephthalate film
Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.
Should Your Business Move to Automatic Flow Wrapping?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
You may benefit from upgrading when:
- Production volumes continue to increase
- Manual packaging slows the production line
- Pack appearance or seal quality is inconsistent
- You need more repeatable packaging results
- Manual packaging is becoming more expensive
A suitable flow wrapper can raise output and produce more uniform packaging.
Key Flow Wrapper Features
Several factors should be considered when selecting flow wrapping machinery.
Important features include:
- Packaging speed
- Product size capacity
- Easy product changeovers more info
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls
- Reliable sealing performance
Your product range, packaging volume and projected demand should guide the final machine specification.
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.
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.
The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.

Flow Wrapping Machine FAQs
What Is a Flow Wrapping Machine Used For?
A flow wrapping machine wraps separate products in flexible packaging film and produces closed pillow-shaped packs. These packs can protect products during storage, transport and retail display.
Can Food Be Packaged with a Flow Wrapper?
Yes. Flow wrapping is widely used for many bakery, confectionery, snack and fresh-food applications. It provides secure and hygienic packaging.
Can a Flow Wrapper Be Used for Manufactured Goods?
Yes. Manufacturers use flow wrapping machinery for a range of healthcare, industrial and consumer products.
How Fast Can Flow Wrapping Machines Operate?
The production rate varies according to product dimensions and machine specification. Many high-performance machines can package thousands of individual items each hour.
