The majority of cartons are delivered folded and side seam sealed to form what is sometime known as a skillet, however. Before the end flaps are folded and closed, on the cartoning machine these skillets are erected and then filled with product.
To add some thing extra to presentation, cartons can be found in a wide variety of designs such as easy-to-open covers, triangular, hexagonal and octagonal dual-walls, body-walls, influx-shaped cartons; and tapered containers.
At their simplest cartoners can be semi-automatic machines which close the flaps of manually erected and filled cartons at low speeds, but at their most sophisticated cartoners are fully automatic machines incorporating pick-and-place product loading or stacking devices, leaflet inserters and coding devices and run at several hundred cartons a minute.
Modern day cartoners have took advantage of the introduction of servo motivated subassemblies, automated reasoning controllers and also computers which allow the horizontal stretch wrapper machines to get dimension transformed immediately and synchronised making use of computer software rather than mechanised transmitting components. However all these features come at extra cost and often a combination of old and new technology can achieve the desired performance.
Cartoning horizontal stretch wrappermachines are employed in most quickly shifting consumer products sectors but specifically cosmetic, food, toiletry and pharmaceutical products in the home, and DIY and documented press businesses.
Cartoning wrapping machines are especially vital within the no-carbonated beverages industry but you should recognise that while the Combibloc carton is made on a version of a mandrel cartoning machine the evidently similar Tetra Brik cartons are made on specific top to bottom form load and seal wrapping machines.
