A automatic flow wrapping system 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.Because of its shape, the finished package is commonly known as a pillow pack.Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for manufacturers processing high volumes of products.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 MachineProducts 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 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?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.High Production SpeedsDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.Repeatable Pack PresentationThe machine applies consistent seals and pack formatting to every item. This can help produce a consistent presentation across a production run.Less Manual HandlingAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore be assigned to other duties.Protection During Storage and TransportThe sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.Flexible Packaging OptionsModern machines can package many product sizes and shapes using different flexible films.Common Flow Wrapping ApplicationsThe process can package products from several different sectors.Typical applications include: Biscuits Cakes, bread products and other bakery goods Sweets, chocolate bars and confectionery Fresh produce Frozen foods Medical products and devices Pharmaceutical products Cosmetics and personal care items Household goods Hardware components Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.Which Packaging Films Work with Flow Wrappers?The correct flexible film will depend on the item being packed and the conditions it must withstand.Available film options include: BOPP film Polyolefin film Polyethylene (PE) PET film The most suitable film depends on the product, required shelf life, desired presentation and production environment.When Should You Invest in a Flow Wrapping Machine?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.Signs that an upgrade may be needed include: click here Production volumes continue to increase Hand wrapping creates a production bottleneck Packaging quality varies between operators Greater consistency is required Manual packaging is becoming more expensive Automatic packaging can improve productivity while maintaining consistent pack quality.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 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?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.The choice will depend on the desired pack format, the product and how it will be stored or transported.Can Flow Wrapping Machinery Be Added to an Existing Production Line?In many cases, 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 increase packaging output without rebuilding the entire production process.Kempner Flow Wrapping SystemsKempner 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.Kempner also provides installation, commissioning, servicing and ongoing technical support.
