A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end 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 produce repeatable sealed packs.1. Product FeedingProducts enter the wrapping section through an automatic conveyor or feeding arrangement.2. Film FormingThe machine guides the film around each product during the packaging process.3. Longitudinal SealingA 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 PackOnce 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 OutputAutomatic systems can package thousands of products per hour, depending on the product and machine specification.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.A Protective Film BarrierFlow wrapping helps protect products from dust, moisture, contamination and physical damage during distribution and storage.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?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 OptionsDifferent film materials can be used according to the packaging requirements.Available film options 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.You may benefit from upgrading when: Your required packaging output is rising Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent read more You need more repeatable packaging results Labour costs are increasing 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.Useful machine features include: Packaging speed Supported product dimensions Fast and straightforward 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.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.Flow wrapping machinery forms film around the product before applying length and end seals.A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.The right method depends on the required appearance, product type and handling conditions after packaging.Can Flow Wrapping Machinery Be Added to an Existing Production Line?In many cases, 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.The available machinery includes horizontal and vertical flow wrappers for food and non-food applications.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.Kempner also provides installation, commissioning, servicing and ongoing technical support.
