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.Unlike manual packaging methods, flow wrapping machines are built for continuous production. 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 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 RatesAutomatic systems can package thousands of products per hour, depending on the product and machine specification.Consistent Packaging QualityThe machine applies consistent seals and pack formatting to every item. This can help produce a consistent presentation across a production run.Less Manual HandlingFlow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore be assigned to other duties.Product ProtectionThe 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.Frequently used films include: Biaxially oriented polypropylene film check here Polyolefin film Polyethylene film Polyethylene terephthalate film Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.Should Your Business Move to Automatic Flow Wrapping?Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.You may benefit from upgrading when: Production volumes continue to increase 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: Maximum production speed Supported product dimensions Fast and straightforward changeovers Photocell registration for printed films Integrated date or batch coding Compatibility with automatic feeding systems Clear operator controls Consistent and dependable seals Your product range, packaging volume and projected demand should guide the final machine specification.What Is the Difference Between Flow Wrapping and Shrink Wrapping?Although both methods use flexible film, the packaging processes are different.A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.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?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 more than 50 years of experience supplying packaging machinery and materials throughout the UK.Its range includes horizontal and vertical flow wrapping systems for food and non-food products.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.The company offers installation, start-up support, servicing and continued technical help.
