Flow Wrapping Machines Explained
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. Film FormingAs 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. Finished ProductOnce sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.What Are the Benefits of Flow Wrapping Machines?Flow wrapping equipment can help manufacturers improve output and produce consistent packs.Fast Packaging OutputFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Consistent Packaging QualityEach product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.Reduced Labour CostsAutomation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.Protection During Storage and TransportThe sealed film can shield products against dirt, moisture, contamination and handling damage during distribution and storage.Packaging for Different ProductsThe equipment can be configured for varied product formats and packaging materials.Common Flow Wrapping ApplicationsFlow wrapping machinery can be used for many food and non-food products.Typical applications include: Biscuits Bakery products Chocolate and confectionery Fresh produce Selected frozen products Medical devices Pharmaceutical products Cosmetics and personal care items Household goods Small industrial and hardware parts Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.Flow Wrapping Film OptionsThe correct flexible film will depend on the item being packed and the conditions it must withstand.Frequently used films include: Biaxially oriented polypropylene film Polyolefin film Polyethylene (PE) PET 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?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.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 read more 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.Important features include: Packaging 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 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 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. Many flow wrapping machines are designed to connect with existing production equipment.Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to add automated packaging without making major changes to the full production line.Flow Wrapping Machinery from KempnerKempner 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.The company offers installation, start-up support, servicing and continued technical help.
