Product description

Poly-Tex is a HDPE woven fabric with a waterproof plastic coating on one side. This laminated fabric has reinforced sides and a reinforced middle area which is obtained during the weaving process on the looms. It stands out from other products for its mechanical strength which makes it significantly resistant to tearing.


Poly-Tex reduces thermic inversions and conveys improved temperature balance because the cover act as a barrier both against solar radiation (short-wavelength IR) and the radiation emitted from the soil and plants (long-wavelength IR). 

Diffused light:
Poly-Tex covers are woven with HDPE flat-tape filament which means they have a three-layer structure formed by the weft threads, the warp threads and the plastic coating. Light that crosses these layers is diffused in all directions. 

Mechanical strength of polytex covers:
Poly-Tex is reinforced along the edges with 5cm wide selvedges produced via an increase in the number of woven threads. The middle area has a 30cm wide reinforcement which is obtained via the same increase in thread count. Pre-cut holes or metal grommets can be applied to the side selvedges, at 50cm intervals, in order to facilitate the fastening of the cover to the structure.

Polytex Weight: 150 g/m2 (± 3%)


  • a balance between intensity and quality of light under the cover with a consequent reduction of shadowed areas
  • a regular growth of the vines with clusters elongated in shape and berries uniform in size
  • a more uniform skin colour of the grape bunches
  • a sharp reduction in sunburning of the leaves that come into contact with the plastic cover as a result of not very high temperatures

Poly-Tex is used to delay and postpone the harvest of almost all varieties of table grapes. It is also used to anticipate and advance the ripening of red grapes, black grapes and Sugraone varieties. It also lends itself as suitable protection for the entire growth and productive cycle.

Exhibitor profile

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.
