Baler yarn, which is also known among farmers as press yarn or alfalfa press yarn, is a product designed to withstand extreme stresses. This yarn must be able to keep the massive and compressed masses of forage that are under the hydraulic pressure of the baler machine coherent for a long time.

Polypropylene press yarn is completely resistant to stretching, ultraviolet rays and chemicals, which makes it suitable for use in fields and harsh working environments. One of the advantages of baler thread for packing synthetic fodder is the non-absorption of moisture. Due to the presence of chemicals, these materials do not retain any moisture and do not rot or tear.
