    Flow Wrapping Knives

    The Flow Wrapping Process

    Flow wrapping knives are used for horizontal flow wrapping processes, whereby the basic principle is that the wrapper packages a product by wrapping it in film. The infeed conveyor delivers the product into the forming area, where a film tube is wrapped around the product, where a finseal is created. This is then where the knives come in. The film tube and product are sent to the cutting head, which makes endseals at the same time as cutting any adjoining wrapped products. The result is that you gain individual packages, which are then distributed to the discharge area, where the packages can either be crayoned at a packing station, or collected for packing later.

    Flow Wrapping Knives

    The flow wrapping knives are used at the endseal stage, usually consisting of a pair of rotating shafts that are equipped with crimpers. The upper crimper has a blade, whilst the lower side has an anvil. Through the motion of rotation, the back of one package is sealed at the same time as the front of the next package, cutting the two products apart with one swift motion. Depending on the type of knives used, the material may be made with a straight or serrated edge. The process works by cutting the material in the centre of the seal to ensure both/all packages are sealed properly, with the speed of the conveyor determining the amount of spacing between the products (this is normally adjustable). .

    Materials

    All our high-performance flow wrapping knives are manufactured in our premium grade PowerEdge EXP500 Steel. This guarantees the best blade performance, and results are less downline, with the blade change time being the minimum possible. These types of knives are able to keep their sharpness despite intense and prolonged use, outperforming a conventional blade between 10 to 20 times. Fitting these flow wrapping knives into the machinery gives you extra strength and extra productivity.

    Equipment Manufactures

    There are many manufacturers that are served by our flow wrapping knives. Common brands include Bosch, Redpack, Fuji, Sandiacre and Tevopharm Machines. Our flow wrapping knives include those for high speed, EXP500 flow wrapping knives, and zig-zag flow wrapping knives.
