Blue impermeable film with oxygen barrier properties, manufactured with multilayer co-extrusion LDPE, and used under silage film to eliminate top and shoulder waste.

Properties and Applications

Used widely, especially in Europe, the process of covering silage with first a thin blue impermeable film, prior to conventionally sheeting with a black cover.

The secondary sheet sucks down onto the silage creating a vacuum, where all oxygen trapped under the cover is absorbed by the natural fermentation process in the clamp.


  • Complete hermeticism, with no top or shoulder waste.

  • For an added cost of less than a standard silage sheet, the usual waste can be eliminated 100%.
