What Is a Flow Wrapping Machine?
A flow wrapping machine is an automated packaging system that encloses products in flexible film. The machine forms a longitudinal seal and two end seals to create a closed package.Because of its shape, the finished package is commonly known as a pillow pack.Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for manufacturers processing high volumes of products.What Is the Flow Wrapping Process?A flow wrapping machine uses a continuous roll of flexible film to produce repeatable sealed packs.1. Products Enter the MachineProducts are carried into the machine by a conveyor or integrated feeding system.2. The Film Is Formed Around the ProductThe packaging film is shaped around each product as it moves through the machine.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 completed pillow pack leaves the machine ready for storage, transport or retail display.Why Use a Flow Wrapping Machine?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.High Production SpeedsDepending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.Repeatable Pack PresentationThe 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.Adaptable Product HandlingThe equipment can be configured for varied product formats and packaging materials.Common Flow Wrapping ApplicationsA 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 Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.Flow Wrapping Film OptionsDifferent film materials can be used according to the packaging requirements.Common materials include: BOPP film Polyolefin packaging film Polyethylene (PE) 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.A flow wrapping machine may be suitable if: Production volumes continue to increase Manual packaging slows the production line Packaging quality varies between operators Greater consistency is required Manual packaging is becoming more expensive Automation may provide steadier production without reducing packaging consistency.What Features Should You Look for in Flow Wrapping Machinery?The correct machine should be chosen according to the product and production requirements.Specifications to review include: Maximum production speed Product size capacity Easy product changeovers Printed-film registration using photocells Date and batch-code printing more info Automatic feeding integration User-friendly controls Reliable sealing performance Machine suitability will be determined by the items being packed, required output and expected business growth.How Do Flow Wrappers Differ from Shrink Wrap Machines?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.Can a Flow Wrapper Integrate with Existing Equipment?Yes. Many flow wrapping machines are designed to connect with existing production equipment.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.Support services include machine installation, commissioning, maintenance and technical assistance.
