A flow wrapping machine 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.The completed package is often called a pillow pack because of its shape.Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for businesses that need to package large quantities efficiently.What Is the Flow Wrapping Process?Flow wrapping machinery 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 PackA 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. Pack ExitThe sealed package exits the machine and can then be stored, distributed or displayed.Advantages of Flow Wrapping MachineryFlow wrapping equipment can help manufacturers improve output and produce consistent packs.Increased Production RatesDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.Uniform Seals and AppearanceEach product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.Reduced Labour CostsFlow 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 warehousing, handling and delivery.Packaging for Different ProductsCurrent flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.What Can Be Packaged Using a Flow Wrapper?The process can package products from several different sectors.Typical applications include: Biscuits Bakery products Sweets, chocolate bars and confectionery Fresh produce Frozen foods Medical devices Pharmaceutical goods Cosmetics and personal care items Domestic and consumer products 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?Different film materials can be used according to the packaging requirements.Frequently used films include: Biaxially oriented polypropylene film Polyolefin film Polyethylene film Polyethylene terephthalate 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?An automatic flow wrapper may become suitable when manual processes start slowing the production line.Signs that an upgrade may be needed include: 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.What Features Should You Look for in Flow Wrapping Machinery?Machine selection requires an assessment of pack format, output and future demand.Important features include: Packaging speed Product size capacity Fast and straightforward changeovers Printed-film registration using photocells Date and batch-code printing website Automatic feeding integration User-friendly controls 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.A flow wrapping machine forms a sealed pillow pack from a continuous roll of 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.Can a Flow Wrapper Integrate with Existing Equipment?In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.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 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.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.Kempner also provides installation, commissioning, servicing and ongoing technical support.
