The weight of one long meter is not always proportional to the actual strength. More important factors are the precision of the production lines` extrusion and the quality of the raw materials used.
It is believed that a net with a large weight (g / m) can withstand loads more than a net with a lower weight per long meter. Indeed, we could think like this five years ago. Then the weight of the net`s long meter was often 13-14 g / m. But at the moment the net with a weight of 10-11 grams is similar in strength to the heavier net that was produced earlier. In addition, modern nets with a weight of 8-9 g / m are produced and tie the bales with high quality. But if we compare modern materials made on modern machines, then the weight of 1 long meter may matter and we will explain it with an example.
For example:
We have 2 rolls of net made on modern equipment. It makes sense that you will make fewer turns around the bale if the net is more reliable.
Option 1: You need to bale hay with a bale diameter of 1.2 meters without using a chopper.
In this case, it is advisable to use a light net.
Option 2: Packing may be provided with the use of a chopper, you need to pack bales with a diameter of 1.6-1.8 m or you need to pack straw.
Under such conditions, it is worth looking towards a heavier net, because when using lightweight mesh, you often need to additionally make 1-2 turns in the press chamber, which entails overspending of material. On straw, for example, manufacturers recommend a minimum of 3.5-4 turns, that is, one additional turn with a lighter mesh is + 25% to the cost of wrapping 1 bale. Although insignificantly, the performance (speed) of the equipment decreases. This is not important if you are packing a few bales, but it becomes important if you need to pack a lot of hay.
Conclusion: It is necessary to choose the optimal version of the material for a specific task and equipment, then you really won’t have to overpay. When choosing a net and a manufacturer, you need to compare each specific case (the quality of the net, the crop that is pressed, the pressure settings in the chamber, the bale diameter, the use of chopping, the serviceability of the equipment) and calculate the cost of packing 1 bale on a specific press and on a specific crop.
