Flow Wrapping Machines Explained
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 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 MachineA 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. Finished ProductOnce sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.What Are the Benefits of Flow Wrapping Machines?Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.Fast Packaging OutputAutomatic systems can package thousands of products per hour, depending on the product and machine specification.Consistent Packaging QualityEach product receives the same seal quality and presentation. This can help produce a consistent presentation across a production run.Reduced Labour CostsFlow 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 OptionsCurrent 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 Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.Flow Wrapping Film OptionsThe correct flexible film will depend on the item being packed and the conditions it must withstand.Common materials include: Biaxially oriented polypropylene film Polyolefin packaging film Polyethylene film Polyethylene terephthalate 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: flow wrapping machines 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.Important features include: Packaging speed Product size capacity Easy product changeovers Printed-film registration using photocells Date and batch-code printing Automatic feeding integration 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.A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.The right method depends on the required appearance, product type and handling conditions after packaging.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.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.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.
