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. Sealing Along the PackA longitudinal seal joins the film beneath or above the product, forming a continuous tube.4. The Pack Is Sealed and SeparatedThe machine creates end seals and then separates each pack from the film web.5. The Completed Pillow PackThe completed pillow pack leaves the machine ready for storage, transport or retail display.What Are the Benefits of Flow Wrapping Machines?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.Increased Production RatesDepending 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.Protection During Storage and TransportThe sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.Flexible Packaging OptionsModern machines can package many product sizes and shapes using different flexible films.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 check here Polyethylene film PET film The most suitable film depends on the product, required shelf life, desired presentation and production environment.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 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 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?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.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 increase packaging output without rebuilding the entire production process.Flow Wrapping Machinery from KempnerKempner has supplied packaging machines and materials across the UK for over five decades.The available machinery includes horizontal and vertical flow wrappers for food and non-food applications.Available options include photocell registration, date or batch coding and machine configurations for specific production needs.Kempner also provides installation, commissioning, servicing and ongoing technical support.
