Flow Wrapping Machines Explained
A flow wrapper 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 finished format is usually described as a pillow pack.Unlike manual packaging methods, flow wrapping machines are built for continuous production. 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 FeedingA conveyor or connected feeding system automatically moves products into the machine.2. Film FormingAs 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 SeparatedCross seals are formed at each end before the package is cut from the continuous film.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 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.Product ProtectionThe sealed film can shield products against dirt, moisture, contamination and handling damage during storage and transport.Adaptable Product HandlingThe equipment can be configured for varied product formats and packaging materials.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 more info 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?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.You may benefit from upgrading when: Production volumes continue to increase Hand wrapping creates a production bottleneck Pack appearance or seal quality is inconsistent You need more repeatable packaging results Labour costs are increasing A suitable flow wrapper can raise output and produce more uniform packaging.How Do You Choose a Flow Wrapping Machine?Machine selection requires an assessment of pack format, output and future demand.Important 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 Reliable sealing performance Your product range, packaging volume and projected demand should guide the final machine specification.Flow Wrapping Versus Shrink WrappingBoth 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.Flow Wrapping Machine IntegrationIn many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.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.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.

These packs can provide protection during handling, distribution and display.Is Flow Wrapping Suitable for Food Products?Yes. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides closed packaging that supports hygienic handling.Are Flow Wrappers Suitable for Non-Food Items?Yes, they can. Manufacturers use flow wrapping machinery for pharmaceutical products, medical devices, hardware, cosmetics and consumer goods.What Is the Speed of a Flow Wrapping Machine?Packaging speed is affected by the equipment model, pack format and item being handled. Many high-performance machines can produce several thousand sealed packs in an hour.
