Silage Films And Stretch Films
Silage films are used primarily to preserve silage, hay and maize. They maintain the nutritional value of the contents and inhibit undesirable fermentation processes. To reach the needed properties that ensure protection throughout the duration of outdoor exposure the films require good resistance against weathering.
Silage, stretch and silo-bags made of PE, EVA and EBA protect a fermented high-moisture fodder that can be fed to livestock. Silage must be firmly packed to minimize oxygen content and prevent spoilage. This makes durability a key requirement. BASF offers a wide range of additives and colorants for these applications.
