AI Technical Summary

Technical Problem

Existing agricultural light barrier films face issues such as inferior outdoor durability, high cost, complexity in application, and adverse effects on plant growth due to UV transmission, leading to reduced crop quality and increased maintenance needs.

Method used

A photo selective light barrier film arrangement that incorporates UV stabilizers and absorbers, along with additives like Tioxide, Aluminum, and Calcium Carbonate, to control UV, PAR, and NIR light transmission, thereby modifying insect behavior and enhancing plant growth while reducing fungal activity.

Benefits of technology

The film arrangement effectively reduces UV and NIR transmission, enhancing plant development by controlling PAR, while also reducing insect infestation and fungal growth, thus improving crop quality and extending the film's durability and cost-effectiveness.

Abstract

The invention discloses a photo selective light barrier film arrangement, which includes a membrane adapted to control the effects of ultraviolet light, photosynthetically activated radiation and near infrared light. The membrane is not only adapted to control the effects of UV light, far and near IR light, but also incorporates additives that will preserve the mechanical integrity of the light barrier whilst exposed to the elements. The membrane includes UV stabilizers and UV absorbers. The UV stabilizers and UV absorbers include at least one or more combination of Hydroxy Benzotriozole (BTA), Hindered Amine Light Stabilizers (HALS), Sorbiton Monostearate, Optical Brightening Agent (Stilbene), Siloxane, Silica, Zeolites, Nanosilver, Calcium Carbonate (CaC03), Tioxide (TI02), Aluminium, Red Pigment, Blue Pigment, Anti-Oxidants and Processing Aids.
