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.Because of its shape, the finished package is commonly known as a pillow pack.Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for production lines that require fast and consistent packaging.How Do Flow Wrapping Machines Work?Flow wrapping machinery uses a continuous roll of flexible film to wrap products at a steady production rate.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. The Length Seal Is FormedThe machine seals the film lengthways so that it surrounds the product in a tube.4. End Sealing and CuttingThe 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.Why Use a Flow Wrapping Machine?Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.High Production SpeedsDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.Uniform Seals and AppearanceProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.Lower Operator RequirementsAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.A Protective Film BarrierA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact 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 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 Polyolefin film read more Polyethylene (PE) Polyethylene terephthalate 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 Labour costs are increasing A suitable flow wrapper can raise output and produce more uniform packaging.Key Flow Wrapper FeaturesSeveral factors should be considered when selecting flow wrapping machinery.Important features include: Packaging speed Product size capacity Easy product changeovers Printed-film registration using photocells Date and batch-code printing Automatic feeding integration User-friendly 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.Businesses should consider presentation, product characteristics and post-production handling when selecting a system.Flow Wrapping Machine IntegrationYes. 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 increase packaging output without rebuilding the entire production process.Kempner Flow Wrapping SystemsKempner 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.Available options include photocell registration, date or batch coding and machine configurations for specific production needs.Support services include machine installation, commissioning, maintenance and technical assistance.
