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.Flow wrappers differ from manual packaging systems because they can operate continuously. This makes the equipment suitable for manufacturers processing high volumes of products.What Is the Flow Wrapping Process?A flow wrapping machine uses a continuous roll of flexible film to produce repeatable sealed packs.1. Product FeedingProducts are carried into the machine by a conveyor or integrated feeding system.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. The Pack Is Sealed and SeparatedThe machine creates end seals and then separates each pack from the film web.5. The Completed Pillow PackThe completed pillow pack leaves the machine ready for storage, transport or retail display.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 RatesAutomatic systems can package thousands of products per hour, depending on the product and machine specification.Consistent Packaging QualityThe machine applies consistent seals and pack formatting to every item. 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 focus on other production tasks.Product ProtectionFlow wrapping helps protect products from dust, moisture, contamination and physical damage during distribution and storage.Adaptable Product HandlingThe 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.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.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 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?An automatic flow wrapper may become suitable when manual processes start slowing the production line.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 Manual packaging is becoming more expensive 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 more info 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.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 increase packaging output without rebuilding the entire production process.Kempner Flow Wrapping SystemsKempner has supplied packaging machines and materials across the UK for over five decades.Kempner supplies both horizontal and vertical machines that can be configured for different product types.Available options include photocell registration, date or batch coding and machine configurations for specific production needs.Kempner also provides installation, commissioning, servicing and ongoing technical support.
