Purity and product safety place the highest demands on silage films. At Zill, we are convinced that virgin-material silage films are essential for producing hygienic, high-quality silage. After all, feed quality is the foundation of food safety and successful dairy farming.
Recycling plastics is an important contribution to sustainability and resource conservation. Recycled materials can be transformed into durable and useful products such as park benches, fence posts, grass grids and construction materials – an excellent application for recycled plastics.
However, when it comes to forage preservation and direct contact with animal feed, different standards apply. In this sensitive area, the use of recycled plastics should be carefully considered, especially when the origin of the material cannot be fully traced. Lower-quality recycled materials may contain unwanted residues or contaminants which, in the worst case, could enter the feed chain. This is a risk that should be avoided wherever possible.
In addition to food and feed safety, virgin-material silage films offer significant quality advantages. They provide higher strength, improved tear resistance and a more uniform material structure. This results in better gas tightness and greater resistance to mechanical stress – both crucial factors for producing high-quality silage.
At the end of the silage season, used cover films can still play an important role in the circular economy. They can be collected and recycled responsibly, providing valuable raw materials for durable secondary products.
The Bottom Line: Virgin-material silage films offer significantly higher safety, reliability and performance for forage preservation – without compromise. Recycling remains important, but it should be applied where it makes the most sense.
