Combi Vapour Layer is a silage cover and underlayer all rolled in to one cover. The convenience of one cover with the benefits of using a 40 micron cling film underlay and a 127 micron UV stabilised outer. The primary oxygen barrier film sheet sucks down onto the silage creating a vacuum, resulting in an air tight clamp with little to no top or shoulder waste. Usual waste can be eliminated by as much as 100% saving hundreds, maybe thousands of dollars in lost silage with the benefit of enhanced silage quality.
