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.Because of its shape, the finished package is commonly known 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.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 FeedingProducts enter the wrapping section through an automatic conveyor or feeding arrangement.2. Film FormingThe machine guides the film around each product during the packaging process.3. Longitudinal SealingThe machine seals the film lengthways so that it surrounds the product in a tube.4. End Sealing and CuttingThe machine creates end seals and then separates each pack from the film web.5. Pack ExitThe 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 SpeedsDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.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 BarrierFlow wrapping helps protect products from dust, moisture, contamination and physical damage during storage and transport.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: Individual or grouped biscuits Cakes, bread products and other bakery goods Chocolate 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.Common materials include: Biaxially oriented polypropylene film Polyolefin packaging 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 Automatic feeding integration User-friendly controls website Reliable sealing performance Machine suitability will be determined by the items being packed, required output and expected business growth.How Do Flow Wrappers Differ from Shrink Wrap Machines?Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.A flow wrapper creates a closed pillow-shaped pack using continuous film.With shrink wrapping, the product is enclosed in film that shrinks when it passes through a heat tunnel.Businesses should consider presentation, product characteristics and post-production handling when selecting a system.Flow Wrapping Machine IntegrationYes. 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 more than 50 years of experience supplying packaging machinery and materials throughout the UK.Kempner supplies both horizontal and vertical machines that can be configured for different product types.Systems may include printed-film controls, coding equipment and layouts adapted to individual applications.Support services include machine installation, commissioning, maintenance and technical assistance.
