A flow wrapper is an automated packaging system that wraps individual products in flexible packaging film. The machine forms long seals and cross seals to create a closed package.The finished format is usually described 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 Does Flow Wrapping Machinery Work?Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.1. Automatic Product FeedingProducts enter the wrapping section through an automatic conveyor or feeding arrangement.2. Film FormingThe machine guides the film around each product during the packaging process.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. 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?Flow 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.Consistent Packaging QualityEach product receives the same seal quality and presentation. This can help maintain a uniform brand appearance.Reduced Labour CostsAutomation reduces the amount of manual handling needed during packaging. 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?Different film materials can be used according to the packaging requirements.Available film options include: BOPP 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: Production volumes continue to increase Manual packaging slows the production line Pack appearance or seal quality is inconsistent check here You need more repeatable packaging results Manual packaging is becoming more expensive Automatic packaging can improve productivity while maintaining consistent pack quality.How Do You Choose a Flow Wrapping Machine?Machine selection requires an assessment of pack format, output and future demand.Important features include: Packaging 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 Consistent and dependable seals Your product range, packaging volume and projected demand should guide the final machine specification.Flow Wrapping Versus Shrink WrappingAlthough both methods use flexible film, the packaging processes are different.A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.The choice will depend on the desired pack format, the product and how it will be stored or transported.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.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.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.
