A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end 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.What Is the Flow Wrapping Process?A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.1. Products Enter the MachineProducts are carried into the machine by a conveyor or integrated feeding system.2. The Film Is Formed Around the ProductThe packaging film is shaped around each product as it moves through the machine.3. The Length Seal Is FormedThe film is sealed along its length to create a continuous tube around the product.4. Cross Sealing and CuttingEnd-sealing jaws close the package before cutting it into an individual pack.5. Finished ProductThe sealed package exits the machine and can then be stored, distributed or displayed.Advantages of Flow Wrapping MachineryMany manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.High Production SpeedsFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Uniform Seals and AppearanceProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.Lower Operator RequirementsAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.Protection During Storage and TransportA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during warehousing, handling and delivery.Flexible Packaging OptionsModern machines can package many product sizes and shapes using different flexible films.Which Products Can Flow Wrapping Machinery Package?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 Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.Which Packaging Films Work with Flow Wrappers?A flow wrapping machine can use several flexible packaging films depending on the product and application.Frequently used films include: Biaxially oriented polypropylene film Polyolefin film Polyethylene (PE) Polyethylene terephthalate 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?An automatic flow wrapper may become suitable when manual processes start slowing the production line.You may benefit from upgrading when: Production volumes continue to increase Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent here You need more repeatable packaging results Labour costs are increasing A suitable flow wrapper can raise output and produce more uniform packaging.Key Flow Wrapper FeaturesSeveral factors should be considered when selecting flow wrapping machinery.Important features include: Packaging speed Product size capacity Easy product changeovers Printed-film registration using photocells Date and batch-code printing 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.What Is the Difference Between Flow Wrapping and Shrink Wrapping?Although both methods use flexible film, the packaging processes are different.A flow wrapper creates a closed pillow-shaped pack using continuous film.Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.The choice will depend on the desired pack format, the product and how it will be stored or transported.Can a Flow Wrapper Integrate with Existing Equipment?Yes. Current flow wrappers may be installed as part of an established production system.Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to raise production capacity without replacing every existing system.Why Choose Kempner for Flow Wrapping Machines?Kempner UK has more than 50 years of experience supplying packaging machinery and materials throughout the UK.Its range includes horizontal and vertical flow wrapping systems for food and non-food products.Systems may include printed-film controls, coding equipment and layouts adapted to individual applications.Support services include machine installation, commissioning, maintenance and technical assistance.
