The balers can be made suitable for the use of plastic wires to knot the bales. Using plastic wires has the major advantage that it does not need to be removed before the baled up materials are being incinerated, as is the case when you use metal wires.

Because the baler needs some adjustments if it is to use plastic wires, among other things with the installation of different twisting fingers and knotting installation, special wire guide wheels and wire roll platforms, it is more expensive.
