A flow wrapper is an automated packaging system that encloses products in 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 businesses that need to package large quantities efficiently.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.Fast Packaging OutputFlow 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 maintain a uniform brand appearance.Lower Operator RequirementsAutomation reduces the amount of manual handling needed during packaging. Staff can therefore spend less time on repetitive packaging work.A Protective Film BarrierA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.Packaging for Different ProductsCurrent flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.What Can Be Packaged Using a Flow Wrapper?A flow wrapper is suitable for a wide selection of food and manufactured goods.Common examples include: Individual or grouped 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 Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.Flow Wrapping Film OptionsThe correct flexible film will depend on the item being packed and the conditions it must withstand.Common materials include: Biaxially oriented polypropylene film Polyolefin film Polyethylene film 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 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 flow wrapping machinery 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. Many flow wrapping machines are designed to connect with existing production equipment.Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to add automated packaging without making major changes to the full production line.Flow Wrapping Machinery from KempnerKempner 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.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.The company offers installation, start-up support, servicing and continued technical help.
