A flow wrapping machine 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 completed package is often called a pillow pack because of its shape.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 machine seals the film lengthways so that it surrounds the product in a tube.4. End Sealing and CuttingEnd-sealing jaws close the package before cutting it into an individual pack.5. Pack ExitThe sealed package exits the machine and can then be stored, distributed or displayed.Why Use a Flow Wrapping Machine?Many 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.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?Flow wrapping machinery can be used for many food and non-food products.Typical applications 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 OptionsDifferent film materials can be used according to the packaging requirements.Available film options include: BOPP film Polyolefin packaging film Polyethylene (PE) 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?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.Signs that an upgrade may be needed include: Your required packaging output is rising Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent Greater consistency is required website 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 Photocell registration for printed films Integrated date or batch coding Compatibility with automatic feeding systems Clear operator controls Consistent and dependable seals 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 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.
