Plastic film for coverning linear soft fruit cultivations

Plastic film for covering linear soft fruit cultivations that bears reinforced sections in terms of thickness (X) along both edges as well as a reinforced section (Y) along a mid-section lengthways, said reinforcement produced by extruding the film with variable thickness across the width or by gluing, welding, sewing additional stripes of the same or different material or by directly extruding or laminating additional material on sections (X) and (Y) or by folding the lengthways edges and welding the fold on the plastic film at the whole section (X) and reinforcing section (Y) separately that is characterised by fact that a plastic cord is glued, welded or extruded along both lengthways sides being partially or entirely inclined in relation to the main lengthways axis with said inclination being constant or changing direction and following a repetitive pattern with period Pi and bearing holes at both sections (X), adjacent to the inclined cord and at the positions that are closer to the edge however towards the side of the cord that is facing the main lengthways axis of the plastic film;

• said cord has a diameter (D) less than 10 mm and due to said inclination of the cord, the cord distributes the exerted load at the whole reinforced area of the plastic film in both longitudinal and traverse directions, thus increasing the strength of the plastic film.
