The majority of cartons are delivered folded and side seam sealed to form what is sometime known as a skillet, however. On the cartoning machine these skillets are erected and then filled with product before the end flaps are closed and folded.
To add something added to demonstration, cartons can be found in a multitude of shapes which includes easy-to-open lids, octagonal, hexagonal and triangular double-wall, framework-walls, wave-designed cartons; and tapered containers.
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, though at their simplest cartoners can be semi-automatic machines which close the flaps of manually filled and erected cartons at low speeds.
Contemporary cartoners have benefited from the creation of servo driven subassemblies, automated reason controllers as well as personal computers which allow the horizontal stretch wrapper machines to get dimension changed immediately and synchronised using software program instead of mechanised transmitting parts. All these features come at extra cost and often a combination of new and old technology can achieve the desired performance, however.
Cartoning horizontal stretch wrappermachines are utilized in every fast relocating customer products sectors but particularly cosmetic, food, toiletry and pharmaceutical products in the home, and Do-it-yourself and recorded mass media sectors.
Cartoning wrapping machines are particularly important within the no-carbonated beverages industry but you should recognise that while the Combibloc carton is produced on the variant of a mandrel cartoning machine the seemingly similar Tetra Brik cartons are designed on unique vertical form load and seal wrapping machines.
