Silage films are mainly used to preserve silage, hay and corn. They maintain the nutritional value of the contents and prevent undesirable fermentation processes. Polyethylene films resist atmospheric agents and guarantee protection during outdoor exposure. Polyethylene film and stretch film are used for silo packaging. With its extraordinary elasticity, stretch film is the best solution for long-term storage of all types of fodder. Stretch protects the grass entirely and prevents oxygen from leaving it.
