A flow wrapping machine 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 completed package is often called a pillow pack because of its shape.Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for businesses that need to package large quantities efficiently.What Is the Flow Wrapping Process?A flow wrapping machine 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. Film FormingThe packaging film is shaped around each product as it moves through the machine.3. The Length Seal Is FormedA 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.Why Use a Flow Wrapping Machine?Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.High Production SpeedsFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Uniform Seals and AppearanceEach 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.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 goods Personal care products Domestic and consumer products Hardware components 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.Common materials include: BOPP film flow wrapping machines Polyolefin packaging film Polyethylene film PET film Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.When Should You Invest in a Flow Wrapping Machine?An automatic flow wrapper may become suitable when manual processes start slowing the production line.You may benefit from upgrading when: Production volumes continue to increase Hand wrapping creates a production bottleneck 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.Key Flow Wrapper FeaturesMachine selection requires an assessment of pack format, output and future demand.Important features include: Packaging speed Product size capacity 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 wrapper creates a closed pillow-shaped pack using continuous 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.Why Choose Kempner for Flow Wrapping Machines?Kempner 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.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.
