In agriculture, gas barrier films are currently used in two main applications
- In soil disinfection by means of fumigant and
- In silage film to preserve cattle’s forage from oxidation and spoilage
Films feature following structure: PE/Orevac®/EVOH/Orevac®/PE with EVOH layer as fumigant barrier layerFilm for soil fumigation with EVOH layer is named TIF or Totally Impermeable Film
Orevac® tie resins (ready to use or concentrate adhesive) impart high adhesion level and film cohesion allowing agricultural film to be mechanically laid down on soilRatio of Orevac® 18341 and OE825 within the tie resin blend ranges from 20 to 30% for TIF film, as well as Evasin 3851F or Evasin 4451F.
