Covering silage with a thin, impermeable film before conventionally sheeting with a normal silage cover is a process used by contractors around the world. Our Combi Cover is a silage cover and underlayer all rolled in to one. Combi Cover provides the same benefits of using a 40-micron cling film underlay and a 127-micron UV-stabilised outer, without having to roll them out as individual covers.

The primary Oxygen Barrier Film sheet sucks down onto the silage to create a vacuum where all oxygen trapped under the cover is absorbed by the natural fermentation. The result is an air-tight clamp, with little to no top or shoulder waste. Usual waste can be eliminated by as much as 100%, saving hundreds or even thousands of dollars in lost silage.

• Users can save up to $5.50 per ton of silage

• Aerobic stability is increased by up to two-and-a-half days, so silage on the face and in front of the cows stays fresh and nutrient-rich for longer

• Combi Vapour covers are specially rolled in a free-falling configuration, enabling both the underlayer and top cover to be easily deployed on the pile in one action

• Dry matter loss in the top 1 meter of silage is reduced by up to 50%
