Flow Wrapping Machines Explained
A automatic flow wrapping system is an automated packaging system that wraps individual products in flexible packaging 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 manufacturers processing high volumes of products.How Does Flow Wrapping Machinery Work?Automatic flow wrapping equipment uses a continuous roll of flexible film to package products quickly and consistently.1. Automatic Product FeedingA conveyor or connected feeding system automatically moves products into the machine.2. Packaging Film PositioningAs the item travels forward, the machine forms the flexible film around it.3. The Length Seal Is FormedThe film is sealed along its length to create a continuous tube around the product.4. Cross Sealing and CuttingEnd-sealing jaws close the package before cutting it into an individual pack.5. Finished ProductThe sealed package exits the machine and can then be stored, distributed or displayed.Advantages of Flow Wrapping MachineryMany 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 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 warehousing, handling and delivery.Packaging for Different ProductsCurrent flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.Which Products Can Flow Wrapping Machinery Package?Flow wrapping machinery can be used for many food and non-food products.Typical applications include: 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 packaging film Polyethylene (PE) PET film The correct material will be determined by the product type, storage period, presentation requirements and production setting.When Is It Time to Use Flow Wrapping Machinery?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.Signs that an upgrade may be needed include: Your required packaging output is rising Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent Greater consistency is required 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.Specifications to review include: Packaging speed Product size capacity here Easy product changeovers Printed-film registration using photocells Date and batch-code printing Automatic feeding integration 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?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 raise production capacity without replacing every existing system.Why Choose Kempner for Flow Wrapping Machines?Kempner UK has more than 50 years of experience supplying packaging machinery and materials throughout the UK.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.Support services include machine installation, commissioning, maintenance and technical assistance.
