A flow wrapper is an automated packaging system that encloses products in flexible film. The machine forms a longitudinal seal and two end 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.How Do Flow Wrapping Machines Work?Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.1. Automatic Product FeedingProducts enter the wrapping section through an automatic conveyor or feeding arrangement.2. Film FormingThe machine guides the film around each product during the packaging process.3. Longitudinal SealingA longitudinal seal joins the film beneath or above the product, forming a continuous tube.4. The Pack Is Sealed and SeparatedThe machine creates end seals and then separates each pack from the film web.5. The Completed Pillow PackThe 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 PresentationProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.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.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 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 film Polyethylene (PE) PET 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?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.Signs that an upgrade may be needed include: Your required packaging output is rising 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?Machine selection requires an assessment of pack format, output and future demand.Useful machine features include: Maximum production speed Supported product dimensions Fast and straightforward changeovers Printed-film registration using photocells Date and batch-code printing Automatic feeding integration click here User-friendly controls Reliable sealing performance 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.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 right method depends on the required appearance, product type and handling conditions after packaging.Flow Wrapping Machine IntegrationIn many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.The machine can work alongside feeding units, conveyor systems and labelling equipment. 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.Available options include photocell registration, date or batch coding and machine configurations for specific production needs.Support services include machine installation, commissioning, maintenance and technical assistance.
