Hail is generally perceived as the main risk to crop yield in fruit agriculture. The increasingly high management costs for fruit farmers mean that they require an efficient and active protective system against possible crop damage caused by hailstones. The most reliable and cost-efficient solution remains the protection of new plantations with anti-hail nets. The use of anti-hail nets allows fruit industry companies to maintain a constant supply to the market by reducing the risk of production loss.

Our leno-weave anti-hail nets are woven using high density polyethylene (HDPE) monofilament that is UV stabilized and contains OX antioxidant additives. Our KRISTAL nets are manufactured in several mesh sizes in order to meet the different needs of each variety, each particular pedoclimate and improve the process of photosynthesis.

The side selvedges and the central part of the nets are reinforced by an increase in thread-count, thus providing a strong and secure fastening system when installing the nets on the support structures.


Hail Protection:
The direct and indirect benefits arising from the use of active protection (anti-hail net) compared to a passive protection method (insurance policy) are known to all:
• Safety of the harvest and fruit without bruising or wounds;
• Protection of the trunks, vine shoots, fruit branches (vital elements for optimal growth) and the young plants (grafts).

Windbreak And Sand Barrier:
The benefits of using a windbreak are also well known and obvious:
• Elimination of shredded leaves and scarred fruit;
• Reduction of snapped branches and broken shoots;
• More uniform flowering and larger amount of fruit which is more consistent in size;
• Elimination of the abrasion caused by sand on the skin of fruits.

Anti-hail nets act as a barrier against soil evapotranspiration. The level of opposition to evapotranspiration is proportional to the density of the net mesh:
• In the summer months this effect is positive because it reduces the water requirement;
• In rainy periods the barrier effect is a negative factor because it reduces air circulation and increases the relative humidity.

Shading And Light Intensity:
During dry and sunny periods Kristal net becomes electrostatically charged and attracts dust particles. This dust that settles on the net helps reduce excessive light intensity during the summer period. With the first autumn rains, the dust is washed away from the net which thus returns to its original transparency.

A correct equilibrium between shade and light intensity promotes a balanced process of photosynthesis that allows plants to absorb nutrients and develop plant tissues.

Standard widths from 0.25 to 6.20 mt. Lengths from 100 to 1800 ml (upon request).
Retilplast can sew nets up to 40 metre in width.

Retilplast S.r.l.



Retilplast Srl, located in Southern Italy, has offered reinforced films and nets for agricultural application since 1975. We manufacture, transform and market a full range of products that help growers protect and improve the quality and quantity of their produce.

Our products find application in Viticulture, Fruticulture, Horticulture and include:

a new series of reinforced films and woven tarpaulins for covering and protecting table grapes, cherries and small wild fruits anti-hail nets windbreak nets sunshade nets and anti-insect nets in widths up to 40 metres wide anti-weed mats pollination nets.
The testing and development of new products and processing methods is vital in order to meet, and often anticipate, market requirements. Retilplast positions itself as a bridge between market needs and the world of raw materials and machinery.

We use the most advanced technologies during the processes of extrusion, weaving and lamination. The careful selection of raw materials meets the high level of quality we have achieved with our products and justifies our company's presence in the most demanding international markets.

Our applied research requires dedicated machines that are versatile and easily configurable. Retilplast and its corporate staff are committed to the continuous research, development, manufacturing and marketing of products that stand out for their very high standards of quality, mechanical strength and durability.

Retilplast uses patented technology to reinforce plastic films and woven tarpaulins that are used on tent-structures as protective covers for table grapes, cherries and soft berry fruits.

This innovation allows us to offer plastic covers with optical and physical properties that previously were difficult to use on tent-structures because of their poor mechanical strength. Customers can now choose the cover that best suits their needs from a wide range of plastic sheets which have varying levels of transmittance, thermicity, diffused light, combined light (diffused and direct) and mechanical strength.


Mechanical strength:
Our patented lateral reinforcement is much more resistant to tearing and tensile forces than the traditional methods used so far in this sector. The edges are reinforced by the application of woven fabric in order to create a selvedge on which we then apply tie-down holes. The pre-made holes facilitate the insertion of hooks and PVC tie-strings that are commonly used to install plastic table-grape and cherry covers.

These pre-cut machine-made holes applied to our new reinforced selvedges are about 45% stronger than metal grommets.

Cost-Efficient Solutions:
The application of holes instead of metal grommets is an innovative technology that creates benefits while minimizing costs. The reinforced edges are perforated at regular and constant intervals which allow for precise correspondence of the holes between two aligned sheets. This results in the use of a single tie-string, of fixed length, to fasten and join two sheets, with the added advantage of keeping consistent the mechanical stress to which the tie-down holes are subjected.

The elimination of metal eyelets also facilitates the process of recycling the covers that have ended their life cycle.
