These threads for big bale presses are used to bind large bales up to 100 x 120 x 300 cm with very high breaking loads and increased elongation percentages. With increased elongation amounts, it enables straw and hay to be pressed at high pressures and to make bales much tighter. The transport of the bale pressed at high pressure with high knot strength holds the bale together against the loads to which the bale is subjected during storage without distributing the bale. The dusting that occurs during the operation of the thread in the press and causes the blade to be blinded is minimized in these threads by means of special production technique. The specially formulated UV additive in the proportions determined according to the waiting times in the open area is automatically weighed during the production of the thread and mixed into the raw material and the UV additive homogeneity is ensured at every point of the thread. Effectiveness of UV; guaranteed by testing in periodically accelerated laboratory conditions. High breaking and knot breaking load, high elongation and knot-free features ensure smooth and smooth operation of large bale presses.
