A flow wrapping machine is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a seal along the length of the pack and seals at both ends to create a closed package.
Because of its shape, the finished package is commonly known 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 wrap products at a steady production rate.
1. Automatic Product Feeding
Products enter the wrapping section through an automatic conveyor or feeding arrangement.
2. Film Forming
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
Cross seals are formed at each end before the package is cut from the continuous film.
5. The Completed Pillow Pack
The completed pillow pack leaves the machine ready for storage, transport or retail display.
Why Use a Flow Wrapping Machine?
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
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 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 distribution and storage.
Adaptable Product Handling
The equipment can be configured for varied product formats and packaging materials.
Common Flow Wrapping Applications
A flow wrapper is suitable for a wide selection of food and manufactured goods.
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
- Personal care products
- Domestic and consumer products
- Hardware components
Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.
Flow Wrapping Film Options
Different film materials can be used according to the packaging requirements.
Common materials include:
- BOPP film
- Polyolefin packaging film
- Polyethylene film
- PET film
The most suitable film depends on the product, required shelf life, desired presentation and production environment.
When Is It Time to Use Flow Wrapping Machinery?
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 get more info
- Pack appearance or seal quality is inconsistent
- You need more repeatable packaging results
- Manual packaging is becoming more expensive
Automatic packaging can improve productivity while maintaining consistent pack quality.
How Do You Choose a Flow Wrapping Machine?
Machine selection requires an assessment of pack format, output and future demand.
Useful machine features include:
- Packaging speed
- Supported product dimensions
- Fast and straightforward changeovers
- Photocell registration for printed films
- Integrated date or batch coding
- Compatibility with automatic feeding systems
- Clear operator controls
- Consistent and dependable seals
The correct choice depends on your products, current production volume and future growth plans.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
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.
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.
The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to increase packaging output without rebuilding the entire production process.

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 many bakery, confectionery, snack and fresh-food applications. It provides secure and hygienic packaging.
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 Many Products Can a Flow Wrapper Package?
Operating speed depends on the machine and the product being packaged. Many high-performance machines can package thousands of individual items each hour.
