What Is a Flow Wrapping Machine?
A flow wrapping machine is an automated packaging system that wraps individual products in flexible packaging 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 businesses that need to package large quantities efficiently.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 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. 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.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 Chocolate and confectionery Fruit and vegetables Frozen foods Medical products and devices Pharmaceutical products Cosmetics and personal care items Household goods Small industrial and hardware parts Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.What Films Can a Flow Wrapping Machine Use?The correct flexible film will depend on the item being packed and the conditions it must withstand.Common materials include: Biaxially oriented polypropylene film Polyolefin packaging film Polyethylene film Polyethylene terephthalate film Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.Should Your Business Move to Automatic Flow Wrapping?Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.A flow wrapping machine may be suitable if: Production volumes continue to increase Manual packaging slows the production line Packaging quality varies between operators website You need more repeatable packaging results Manual packaging is becoming more expensive Automation may provide steadier production without reducing packaging consistency.What Features Should You Look for in Flow Wrapping Machinery?The correct machine should be chosen according to the product and production requirements.Specifications to review include: Maximum production speed Supported product dimensions 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.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 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.
