What Is a Flow Wrapping Machine?
A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms long seals and cross seals to create a closed package.The finished format is usually described 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 manufacturers processing high volumes of products.How Does Flow Wrapping Machinery Work?A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.1. Products Enter the MachineA conveyor or connected feeding system automatically moves products into the machine.2. Packaging Film PositioningAs the item travels forward, the machine forms the flexible film around it.3. Sealing Along the PackThe 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 sealed package exits the machine and can then be stored, distributed or displayed.Advantages of Flow Wrapping MachineryMany 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.Repeatable Pack PresentationProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.Less Manual HandlingFlow wrapping machinery limits the need for employees to wrap every product by hand. 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 storage and transport.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.Products frequently packaged in this way include: Individual or grouped 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.Common materials include: Biaxially oriented polypropylene film Polyolefin packaging film Polyethylene film Polyethylene terephthalate film The most suitable film depends on the product, required shelf life, desired presentation and production environment.Should Your Business Move to Automatic Flow Wrapping?Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.A flow wrapping machine may be suitable if: 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 Automation may provide steadier production without reducing packaging consistency.What Features Should You Look for in Flow Wrapping Machinery?The correct machine should be chosen according to the product and production requirements.Useful machine 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 click here Consistent and dependable seals The correct choice depends on your products, current production volume and future growth plans.How Do Flow Wrappers Differ from Shrink Wrap Machines?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 a Flow Wrapper Integrate with Existing Equipment?In many cases, yes. Current flow wrappers may be installed as part of an established production system.Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to add automated packaging without making major changes to the full production line.Flow Wrapping Machinery from KempnerKempner UK has supplied packaging machines and materials across the UK for over five decades.The available machinery includes horizontal and vertical flow wrappers for food and non-food applications.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.Support services include machine installation, commissioning, maintenance and technical assistance.
