A flow wrapper is an automated packaging system that encloses products in flexible film. The machine forms a longitudinal seal and two end seals 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 enter the wrapping section through an automatic conveyor or feeding arrangement.2. The Film Is Formed Around the ProductThe machine guides the film around each product during the packaging process.3. Longitudinal SealingThe machine seals the film lengthways so that it surrounds the product in a tube.4. Cross Sealing and CuttingEnd-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.Advantages of Flow Wrapping MachineryFlow wrapping equipment can help manufacturers improve output and produce consistent packs.Fast Packaging OutputAutomatic systems can package thousands of products per hour, depending on the product and machine specification.Repeatable Pack PresentationProducts pass through the same controlled sealing process. This can help keep retail packs neat and recognisable.Less Manual HandlingAn automated system reduces hands-on work throughout the wrapping process. Staff can therefore spend less time on repetitive packaging work.A Protective Film BarrierA closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.Adaptable Product HandlingModern 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.Common examples include: Individual or grouped biscuits Bakery products Chocolate and confectionery Fruit and vegetables Frozen foods Medical products and devices Pharmaceutical goods Personal care products Domestic and consumer products Small industrial and hardware parts Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.Which Packaging Films Work with Flow Wrappers?A flow wrapping machine can use several flexible packaging films depending on the product and application.Available film options include: BOPP film Polyolefin packaging film Polyethylene film PET 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.Signs that an upgrade may be needed include: get more info Production volumes continue to increase Manual packaging slows the production line 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?Several factors should be considered when selecting flow wrapping machinery.Specifications to review 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 WrappingFlow 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.A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.Businesses should consider presentation, product characteristics and post-production handling when selecting a system.Flow Wrapping Machine IntegrationYes. 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 increase packaging output without rebuilding the entire production process.Why Choose Kempner for Flow Wrapping Machines?Kempner UK has more than 50 years of experience supplying packaging machinery and materials throughout the UK.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.Support services include machine installation, commissioning, maintenance and technical assistance.
