A flow wrapper is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end seals to create a closed package.The completed package is often called a pillow pack because of its shape.Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for businesses that need to package large quantities efficiently.How Do Flow Wrapping Machines Work?Flow wrapping machinery 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. Film FormingThe packaging film is shaped around each product as it moves through the machine.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 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?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.Repeatable Pack PresentationThe 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.Protection During Storage and TransportThe sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.Flexible Packaging OptionsModern 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.Typical applications include: Biscuits Cakes, bread products and other bakery goods 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.Flow Wrapping Film OptionsDifferent film materials can be used according to the packaging requirements.Common materials 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 Is It Time to Use Flow Wrapping Machinery?Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.Signs that an upgrade may be needed include: Your required packaging output is rising Manual packaging slows the production line Packaging quality varies between operators Greater consistency is required 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 Printed-film registration using photocells here 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.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. Current flow wrappers may be installed as part of an established production system.The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.Why Choose Kempner for Flow Wrapping Machines?Kempner has more than 50 years of experience supplying packaging machinery and materials throughout the UK.Its range includes horizontal and vertical flow wrapping systems for food and non-food products.Systems may include printed-film controls, coding equipment and layouts adapted to individual applications.Support services include machine installation, commissioning, maintenance and technical assistance.
