The bale press net must comply with several quality criteria:
Enough strength. It is necessary that the net could securely hold the mold of the baler. As the equipment is pressing the hay quite tightly, it is important to make a sufficient number of the packaging turns material so the workpiece is not damaged due to the pressure inside. For reliable bale fixation, it’s would be enough 2.5-4 turns of the bale with a net, but it’s depending on the diameter and the material that being pressed.
Smooth surface. This is especially important for subsequent packaging into agrostretch film. The hay stalks, that laid down in different directions can damage it and this will disturb the anaerobic environment inside.
The good strength can bring the economy of the time and material as it’s can reduce the number of turns of the bale mesh. This depends on the fact that the lower the tensile strength, it means that the baler has to make more turns. That’s why the higher quality of the net bring you a cheaper price of packaging and help you to done with cleaning more faster. In the conclusion, we should say that the price of the baler mesh cannot be the main point when you chose it.
For the packaging of hay Polypak net it would be enough 2-2,5 turns, but for straw we recommend to add 1-1.5 turns over, because the pressure inside in such bale will be higher. Such a small number of turns with the packaging material are more economical. And this is possible due to the high quality of the mesh.
The mesh for hay produced of high-quality polyethylene and includes a special stabilizer to protect against UV rays, which will even better protect the feed when it’s stored in the field. The minimum burst force declared by the manufacturer is 270 kg.
