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 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 Do Flow Wrapping Machines Work?Flow wrapping machinery uses a continuous roll of flexible film to produce repeatable sealed packs.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. 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?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.Increased Production RatesAutomatic systems can package thousands of products per hour, depending on the product and machine specification.Consistent Packaging QualityThe 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.Flexible Packaging OptionsModern machines can package many product sizes and shapes using different flexible films.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 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 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 here Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent You need more repeatable packaging results Manual packaging is becoming more expensive Automatic packaging can improve productivity while maintaining consistent pack quality.How Do You Choose a Flow Wrapping Machine?Machine selection requires an assessment of pack format, output and future demand.Useful machine features include: Maximum production speed Supported product dimensions Fast and straightforward changeovers Photocell registration for printed films Integrated date or batch coding Compatibility with automatic feeding systems 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?Both systems package products in flexible material, although their operating methods differ.Flow wrapping machinery forms film around the product before applying length and end seals.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 add automated packaging without making major changes to the full production line.Flow Wrapping Machinery from KempnerKempner UK has supplied packaging machines and materials across the UK for over five decades.Its range includes horizontal and vertical flow wrapping systems for food and non-food products.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.The company offers installation, start-up support, servicing and continued technical help.
