3 Sealing

The silage producer faces a myriad of choices of plastic films that aid in the preservation of the silage. These include conventional black and white polyethylene film and oxygen barrier film. There are several differences in their design, composition and manufacturing process that influence their ability to effectively exclude oxygen. This can have a major effect on the outcome of your silage.

By covering the silage bunker or bun with a normal black and white polyethylene film, we may have an effective way to prevent water from entering the silage, but not necessarily oxygen. Viewed under a microscope, the normal black and white film contains microscopic holes that will allow oxygen to infiltrate the silage, often causing spoilage in the top 60cm – 90cm of the bunker or bun. Limiting oxygen infiltration using an oxygen barrier plastic (second image) consisting of at least 7, and preferably 9 layers of film, is the single most important factor in maintaining silage quality and reducing wastage.
