A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms long seals and cross seals 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 production lines that require fast and consistent packaging.
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
The film is sealed along its length to create a continuous tube around the product.
4. Cross Sealing and Cutting
End-sealing jaws close the package before cutting it into an individual pack.
5. Finished Product
The sealed package exits the machine and can then be stored, distributed or displayed.
Advantages of Flow Wrapping Machinery
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
High Production Speeds
Flow wrapping machinery can process thousands of products every hour when the equipment and application allow.
Uniform Seals and Appearance
Products pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.
Less Manual Handling
An automated system reduces hands-on work throughout the wrapping process. Staff can therefore be assigned to other duties.
Protection During Storage and Transport
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.
Common Flow Wrapping Applications
The process can package products from several different sectors.
Products frequently packaged in this way include:
- Biscuits
- Cakes, bread products and other bakery goods
- Chocolate 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
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?
The correct flexible film will depend on the item being packed and the conditions it must withstand.
Common materials include:
- flow wrapping machine
- Biaxially oriented polypropylene film
- Polyolefin packaging film
- Polyethylene film
- Polyethylene terephthalate 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:
- 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
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.
Specifications to review include:
- Maximum production speed
- Supported product dimensions
- Fast and straightforward changeovers
- Photocell registration for printed films
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls
- Reliable sealing performance
Machine suitability will be determined by the items being packed, required output and expected business growth.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
Both systems package products in flexible material, although their operating methods differ.
Flow wrapping machinery forms film around the product before applying length and end seals.
With shrink wrapping, the product is enclosed in film that shrinks when it passes through a heat tunnel.
The right method depends on the required appearance, product type and handling conditions after packaging.
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 raise production capacity without replacing every existing system.

Flow Wrapping Machine FAQs
What Is the Purpose of Flow Wrapping Machinery?
A flow wrapping machine packages individual products in flexible film to form sealed pillow packs. These packs can provide protection during handling, distribution and display.
Is Flow Wrapping Suitable for Food Products?
Yes. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides closed packaging that supports hygienic handling.
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.
What Is the Speed of a Flow Wrapping Machine?
Operating speed depends on the machine and the product being packaged. Many high-performance machines can wrap several thousand products per hour.
