What Is a Flow Wrapping Machine?
A flow wrapping machine 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.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?Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.1. Automatic 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 SealingThe 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?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.Repeatable Pack PresentationProducts 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.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.Common materials include: BOPP film Polyolefin packaging film Polyethylene film PET film The most suitable film depends on the product, required shelf life, desired presentation and production environment.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: Packaging speed Product size capacity get more info 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 wrapping machine forms a sealed pillow pack from a continuous roll of 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 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.The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.Why Choose Kempner for Flow Wrapping Machines?Kempner 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.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.
