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?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 PackOnce 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?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 HandlingAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore be assigned to other duties.Protection During Storage and TransportA 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.Which Products Can Flow Wrapping Machinery Package?Flow wrapping machinery can be used for many food and non-food products.Typical applications include: Individual or grouped biscuits Bakery products Sweets, chocolate bars and confectionery Fresh produce Selected frozen products Medical devices Pharmaceutical goods Cosmetics and personal care items Household goods Small industrial and hardware parts Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.What Films Can a Flow Wrapping Machine Use?The correct flexible film will depend on the item being packed and the conditions it must withstand.Frequently used films include: read more Biaxially oriented polypropylene film Polyolefin film Polyethylene (PE) Polyethylene terephthalate 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: 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.What Features Should You Look for in Flow Wrapping Machinery?The correct machine should be chosen according to the product and production requirements.Specifications to review include: Maximum production speed Supported product dimensions Easy product changeovers Printed-film registration using photocells Date and batch-code printing Automatic feeding integration User-friendly controls Reliable sealing performance The correct choice depends on your products, current production volume and future growth plans.How Do Flow Wrappers Differ from Shrink Wrap Machines?Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.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.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. Flow wrapping machinery can often be integrated with equipment already in use.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 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.Support services include machine installation, commissioning, maintenance and technical assistance.
