Have you ever heard about “cracking” in agriculture?
The English term comes from the word “crack = breaking” as we are reminded by the sound of its pronunciation.

Basically cracking is caused by physiological imbalances of the plant, often deficiencies or excesses of nutrients. Consider for example when, after a period of severe drought, a violent thunderstorm that hits the crops restores the water level and nutrients that were missing for a long time … but in an exaggerated way.

The increase in cell tension and pulp volume of fruits causes an excessive expansion of the epidermis of the skin and its breaking.
The possible presence of wind can only worsen such situation.

Besides protecting crops from the effects of adverse meteorological phenomena, farmers need to protect their cultivations also from damages caused by insects and birds. A very effective solution to the problem lies in nets made of high density polyethylene.
They are fixed and laid manually on a structure previously prepared.

If in the form of thin meshes, the protections also perform an important shading function, helping to anticipate or postpone the maturation of crops, while ensuring a uniform diffusion of sun rays.

For the production of agricultural protective nets VIBA can offer its VIBATAN® HDPE UV MASTER 04773 an innovative masterbatch which contains a tertiary polymeric HALS in combination with a UV synergic stabilizer and with antioxidant agents, all on a high density polyethylene carrier.

The product has been developed for the extrusion of high density polyethylene monofilament:
its estimated life span is of about 10 years with a resistance of 1000 ppm of Sulphur, 60 ppm of Chlorine and 45 ppm of Iron.

Its special HALS performs a very good stability to heat and light, not only during processing, but also for all the life cycle of the end product. It is also more resistant to aggressive agents and is therefore suitable for exposure in extreme conditions.
