Economical Multi-lane Production from a Single Layflat Tube

Designed originally to maximise the full working width of the Harnden range of servo driven bag making machines, giving a more all round profitable output.
Extrusion 1 wide reel of film blown instead of several smaller.
Printing 1 reel means less time through printer.
Bag Making Less down time through fewer reel changes and more bags per cycle output.
