How to recognize a good trellis net, and how to spot a poor quality oneHORTOMALLAS gives you tips on how to recognize a good trellis net and spot a poor quality one, as a poorly manufactured product will cause enormous damages to your crops as it can collapse and destroy months of work and the possibility to make money! Firstly one must understand that polypropylene is the best type of polymer to produce netting to be used as plant support in commercial agribusinesses. After extrusion, the net is stretched either in hot water or in a long hot air oven where the molecules are stretched and oriented . This orienting phase is where the molecules are aligned parallely in a very tight manner as compared to the chaotic simple extrusion stage where molecules are simply placed next to each others but have no real strength to them. An aligned (oriented) polymeric structure acquires physical strength characteristics much greater than an extruded net. Once we grasp this basic concept we will be able to distinguish a good product from one that will not perform as needed once installed in the field as the tensile characteristics will not suffice to stand the weight of plants loaded with fruits under wind and rain conditions, and under the constant decay of UV rays from the sun. To begin with HORTOMALLAS is only manufactured from virgin PP, you may notice this from the high mesh gloss of its white color. A virgin plastic will always be spotted at it is able to reflect light much more than an opaque recycled polymer (and by the way a recycle polymer will NEVER have the same physical strength characteristics as one using new PP pellets). A trellis and tutor net made out of a low quality and recycled polymer will have a dull reflection, even if just taken out of the package it will look like it was left out in the dust for days. These poor quality net will only cause problems and losses, be wise and chose your nets properly.
