A flow wrapper 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 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. Product FeedingProducts are carried into the machine by a conveyor or integrated feeding system.2. Packaging Film PositioningAs the item travels forward, the machine forms the flexible film around it.3. The Length Seal Is FormedThe film is sealed along its length to create a continuous tube around the product.4. The Pack Is Sealed and SeparatedEnd-sealing jaws close the package before cutting it into an individual pack.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?Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.High Production SpeedsFlow wrapping machinery can process thousands of products every hour when the equipment and application allow.Repeatable Pack PresentationThe machine applies consistent seals and pack formatting to every item. This can help keep retail packs neat and recognisable.Reduced Labour CostsFlow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore focus on other production tasks.Product ProtectionThe sealed film can shield products against dirt, moisture, contamination and handling damage during distribution and storage.Packaging for Different ProductsThe equipment can be configured for varied product formats and packaging materials.What Can Be Packaged Using a Flow Wrapper?A flow wrapper is suitable for a wide selection of food and manufactured goods.Products frequently packaged in this way include: Individual or grouped biscuits Cakes, bread products and other bakery goods Chocolate and confectionery Fruit and vegetables Frozen foods Medical devices Pharmaceutical goods Cosmetics and personal care items Household goods Small industrial and hardware parts Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.Flow Wrapping Film OptionsThe correct flexible film will depend on the item being packed and the conditions it must withstand.Available film options include: BOPP 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.When Should You Invest in a Flow Wrapping Machine?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.A flow wrapping machine may be suitable if: Production volumes continue to increase Hand wrapping creates a production bottleneck Packaging quality varies between operators You need more repeatable packaging results Labour costs are increasing Automation may provide steadier production without reducing packaging consistency.Key Flow Wrapper FeaturesThe correct machine should be chosen according to the product and production requirements.Important features include: Packaging speed Supported product dimensions flow wrapping machines Fast and straightforward changeovers Photocell registration for printed films 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.Flow Wrapping Versus Shrink WrappingBoth systems package products in flexible material, although their operating methods differ.A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.Businesses should consider presentation, product characteristics and post-production handling when selecting a system.Can a Flow Wrapper Integrate with Existing Equipment?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.Kempner Flow Wrapping SystemsKempner has more than 50 years of experience supplying packaging machinery and materials throughout the UK.Kempner supplies both horizontal and vertical machines that can be configured for different product types.Machines can be supplied with printed-film registration, optional coding systems and tailored configurations.Kempner also provides installation, commissioning, servicing and ongoing technical support.
