What Is a Flow Wrapping Machine?
A flow wrapping machine is an automated packaging system that wraps individual products in flexible packaging film. The machine forms long seals and cross seals to create a closed package.The finished format is usually described as a pillow pack.Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for businesses that need to package large quantities efficiently.What Is the Flow Wrapping Process?Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.1. Product FeedingProducts 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 CuttingCross seals are formed at each end before the package is cut from the continuous film.5. Finished ProductOnce sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.Advantages of Flow Wrapping MachineryFlow wrapping equipment can help manufacturers improve output and produce consistent packs.Increased Production RatesDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.Repeatable Pack PresentationProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.Lower Operator RequirementsAutomation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.Protection During Storage and TransportA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.Adaptable Product HandlingThe equipment can be configured for varied product formats and packaging materials.Common Flow Wrapping ApplicationsA 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 Sweets, chocolate bars and confectionery Fresh produce Selected frozen products Medical devices Pharmaceutical goods Personal care products Domestic and consumer products 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.Common materials include: Biaxially oriented polypropylene film Polyolefin packaging film more info Polyethylene film Polyethylene terephthalate film Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.Should Your Business Move to Automatic Flow Wrapping?Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.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 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: Packaging speed Product size capacity Easy product changeovers Photocell registration for printed films Integrated date or batch coding Compatibility with automatic feeding systems Clear operator controls Reliable sealing performance Your product range, packaging volume and projected demand should guide the final machine specification.Flow Wrapping Versus Shrink WrappingAlthough both methods use flexible film, the packaging processes are different.A flow wrapping machine forms a sealed pillow pack from a continuous roll of 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.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.Flow Wrapping Machinery from KempnerKempner has supplied packaging machines and materials across the UK for over five decades.The available machinery includes horizontal and vertical flow wrappers for food and non-food applications.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.Kempner also provides installation, commissioning, servicing and ongoing technical support.
