Flow Wrapping Machines Explained
A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms a seal along the length of the pack and seals at both ends 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 manufacturers processing high volumes of products.How Does Flow Wrapping Machinery Work?A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.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 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.What Can Be Packaged Using a Flow Wrapper?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 Packaging quality varies between operators Greater consistency is required Labour costs are increasing Automation may provide steadier production without reducing packaging consistency.Key Flow Wrapper FeaturesSeveral factors should be considered when selecting flow wrapping machinery.Specifications to review include: flow wrapping machines 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.Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.Businesses should consider presentation, product characteristics and post-production handling when selecting a system.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.
