A flow wrapper is an automated packaging system that wraps individual products in flexible packaging film. The machine forms long seals and cross seals to create a closed package.Because of its shape, the finished package is commonly known as a pillow pack.Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for production lines that require fast and consistent packaging.What Is the Flow Wrapping Process?A flow wrapping machine uses a continuous roll of flexible film to wrap products at a steady production rate.1. Products Enter the MachineA conveyor or connected feeding system automatically moves products into the machine.2. Film FormingAs the item travels forward, the machine forms the flexible film around it.3. Longitudinal SealingThe film is sealed along its length to create a continuous tube around the product.4. The Pack Is Sealed and SeparatedThe 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?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.Fast Packaging OutputFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Repeatable Pack PresentationEach product receives the same seal quality and presentation. This can help produce a consistent presentation across a production run.Reduced Labour CostsFlow wrapping machinery limits the need for employees to wrap every product by hand. 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 storage and transport.Packaging for Different ProductsModern machines can package many product sizes and shapes using different flexible films.What Can Be Packaged Using a Flow Wrapper?A flow wrapper is suitable for a wide selection of food and manufactured goods.Common examples include: Individual or grouped biscuits Cakes, bread products and other bakery goods Chocolate and confectionery Fresh produce Frozen foods Medical devices Pharmaceutical products Personal care products Household goods Hardware components Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.Flow Wrapping Film OptionsThe correct flexible film will depend on the item being packed and the conditions it must withstand.Available film options include: Biaxially oriented polypropylene film Polyolefin film Polyethylene (PE) flow wrap machine Polyethylene terephthalate film The correct material will be determined by the product type, storage period, presentation requirements and production setting.When Should You Invest in a Flow Wrapping Machine?Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.Signs that an upgrade may be needed include: Production volumes continue to increase Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent Greater consistency is required Labour costs are increasing Automatic packaging can improve productivity while maintaining consistent pack quality.Key Flow Wrapper FeaturesThe correct machine should be chosen according to the product and production requirements.Important features include: Packaging speed Product size capacity Fast and straightforward changeovers Photocell registration for printed films Integrated date or batch coding Automatic feeding integration User-friendly controls Consistent and dependable seals The correct choice depends on your products, current production volume and future growth plans.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.Flow wrapping machinery forms film around the product before applying length and end seals.A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.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?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 add automated packaging without making major changes to the full production line.Kempner Flow Wrapping SystemsKempner 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.
