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.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 enter the wrapping section through an automatic conveyor or feeding arrangement.2. The Film Is Formed Around the ProductThe 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 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 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.Protection During Storage and TransportA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during warehousing, handling and delivery.Flexible Packaging OptionsModern machines can package many product sizes and shapes using different flexible films.Which Products Can Flow Wrapping Machinery Package?The process can package products from several different sectors.Products frequently packaged in this way include: Biscuits Cakes, bread products and other bakery goods Chocolate and confectionery Fruit and vegetables Frozen foods Medical products and devices Pharmaceutical products Cosmetics and personal care items Household goods Small industrial and hardware parts Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.What Films Can a Flow Wrapping Machine Use?The correct flexible film will depend on the item being packed and the conditions it must withstand.Frequently used films 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.Should Your Business Move to Automatic Flow Wrapping?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 Manual packaging is becoming more expensive A suitable flow wrapper can raise output and produce more uniform packaging.Key Flow Wrapper FeaturesMachine selection requires an assessment of pack format, output and future demand.Useful machine features include: Packaging speed Supported product dimensions Fast and straightforward changeovers Printed-film registration using photocells Date and batch-code printing get more info Automatic feeding integration User-friendly controls Reliable sealing performance Your product range, packaging volume and projected demand should guide the final machine specification.What Is the Difference Between Flow Wrapping and Shrink Wrapping?Both systems package products in flexible material, although their operating methods differ.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.The choice will depend on the desired pack format, the product and how it will be stored or transported.Flow Wrapping Machine IntegrationIn 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.Why Choose Kempner for Flow Wrapping Machines?Kempner UK 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.Kempner also provides installation, commissioning, servicing and ongoing technical support.
