A flow wrapper is an automated packaging system that encloses products in flexible film. The machine forms a seal along the length of the pack and seals at both ends 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?A flow wrapping machine uses a continuous roll of flexible film to produce repeatable sealed packs.1. Products Enter the MachineA conveyor or connected feeding system automatically moves products into the machine.2. Packaging Film PositioningThe machine guides the film around each product during the packaging process.3. Longitudinal SealingThe 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 completed pillow pack leaves the machine ready for storage, transport or retail display.What Are the Benefits of Flow Wrapping Machines?Flow wrapping equipment can help manufacturers improve output and produce consistent packs.Increased Production RatesFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Consistent Packaging QualityEach product receives the same seal quality and presentation. This can help produce a consistent presentation across a production run.Less Manual HandlingAutomation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.Product ProtectionThe sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.Flexible Packaging OptionsCurrent 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.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 products and devices Pharmaceutical goods Personal care products 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.Available film options include: BOPP film Polyolefin packaging film Polyethylene film Polyethylene terephthalate film The correct material will be determined by the product type, storage period, presentation requirements and production setting.When Is It Time to Use Flow Wrapping Machinery?An automatic flow wrapper may become suitable when manual processes start slowing the production line.Signs that an upgrade may be needed include: Your required packaging output is rising Manual packaging slows the production line Pack appearance or seal quality is inconsistent Greater consistency is required Manual packaging is becoming more expensive A suitable flow wrapper can raise output and produce more uniform packaging.Key Flow Wrapper FeaturesThe correct machine should be chosen according to the product and production requirements.Useful machine features include: Maximum production speed Product size capacity Easy product changeovers get more info Printed-film registration using photocells Date and batch-code printing Compatibility with automatic feeding systems Clear operator controls Reliable sealing performance Machine suitability will be determined by the items being packed, required output and expected business growth.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.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.Can Flow Wrapping Machinery Be Added to an Existing Production Line?In many cases, yes. Current flow wrappers may be installed as part of an established production system.Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to increase packaging output without rebuilding the entire production process.Kempner Flow Wrapping SystemsKempner has supplied packaging machines and materials across the UK for over five decades.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.The company offers installation, start-up support, servicing and continued technical help.
