Flow Wrapping Machines Explained
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.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 package products quickly and consistently.1. Automatic Product FeedingA 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 PackA longitudinal seal joins the film beneath or above the product, forming a continuous tube.4. The Pack Is Sealed and SeparatedCross seals are formed at each end before the package is cut from the continuous film.5. The Completed Pillow PackThe completed pillow pack leaves the machine ready for storage, transport or retail display.What Are the Benefits of Flow Wrapping Machines?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.Increased Production RatesDepending 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.Lower Operator RequirementsAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.A Protective Film BarrierFlow wrapping helps protect products from dust, moisture, contamination and physical damage during distribution and storage.Adaptable Product HandlingThe equipment can be configured for varied product formats and packaging materials.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 Bakery products Sweets, chocolate bars and confectionery Fresh produce Selected frozen products Medical 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.Frequently used films 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 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: get more info Your required packaging output is rising Manual packaging slows the production line 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.How Do You Choose a Flow Wrapping Machine?Machine selection requires an assessment of pack format, output and future demand.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 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.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.Systems may include printed-film controls, coding equipment and layouts adapted to individual applications.Support services include machine installation, commissioning, maintenance and technical assistance.

These packs can provide protection during handling, distribution and display.Is Flow Wrapping Suitable for Food Products?Yes. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides closed packaging that supports hygienic handling.Can Flow Wrapping Machinery Package Non-Food Products?Yes. Manufacturers use flow wrapping machinery for medical items, pharmaceuticals, small components, personal care goods and household products.How Many Products Can a Flow Wrapper Package?Operating speed depends on the machine and the product being packaged. Many high-performance machines can wrap several thousand products per hour.
