A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms long seals and cross seals to create a closed package.
The completed package is often called a pillow pack because of its shape.
Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for manufacturers processing high volumes of products.
How Do Flow Wrapping Machines Work?
Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.
1. Product Feeding
Products enter the wrapping section through an automatic conveyor or feeding arrangement.
2. The Film Is Formed Around the Product
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
The machine creates end seals and then separates each pack from the film web.
5. Pack Exit
The completed pillow pack leaves the machine ready for storage, transport or retail display.
Why Use a Flow Wrapping Machine?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
High Production Speeds
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 keep retail packs neat and recognisable.
Lower Operator Requirements
An automated system reduces hands-on work throughout the wrapping process. 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
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
- 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.
Common materials include:
- Biaxially oriented polypropylene film
- Polyolefin film
- Polyethylene (PE)
- PET film
Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.
When Should You Invest in a Flow Wrapping Machine?
Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.
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
- Manual packaging is becoming more expensive
A suitable flow wrapper can raise output and produce more uniform packaging.
Key Flow Wrapper Features
The correct machine should be chosen according to the product and production requirements.
Useful machine features include:
- Packaging speed
- Product size capacity
- Easy product changeovers
- Printed-film registration using photocells
- Integrated date or batch coding click here
- Compatibility with automatic feeding systems
- Clear operator controls
- Reliable sealing performance
Machine suitability will be determined by the items being packed, required output and expected business growth.
Flow Wrapping Versus Shrink Wrapping
Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.
Flow wrapping machinery forms film around the product before applying length and end seals.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
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. Current flow wrappers may be installed as part of an established production system.
Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to add automated packaging without making major changes to the full production line.

Questions About Flow Wrapping Machinery
What Does a Flow Wrapper Package?
A flow wrapping machine creates sealed film packs around individual items. These packs can help shield items while they are stored, delivered or presented for sale.
Are Flow Wrappers Used for Food Packaging?
Yes, they are. Flow wrapping is widely used for bakery goods, confectionery, snacks and fresh produce. It provides a hygienic sealed pack.
Can Flow Wrapping Machinery Package Non-Food Products?
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.
