Silage Covers

Guaranteed performance for your investment

New technology polymer combined with state of the art extrusion techniques have significantly increased the field performance of Donaghys silage covers over traditional cover options.  The 7 layer SmartStructureâ„¢technology ensures that Donaghys' heavy silage covers are less likely to tear or puncture during the handling and covering operation making them tougher and stronger than traditional covers. 

Donaghys' premium covers are manufactured by AT Plastics, world leaders in the manufacture of silage film and at the leading edge of silage film developments. We also supply covers from European manufacturers. All our silage covers are UV stabilised for New Zealand conditions and are guaranteed for a minimum of 12 months in the field.

Premium Bulk Rolls

Donaghys Premium Bulk rolls utilise the SmartStructure™multi layer extrusion technology for long term protection against the elements. These stronger, tougher covers are less likely to tear or puncture during the handling and covering operation.

Premium black/white silage covers provide outstanding reflective properties - white on the outside to reflect the light and reduce heat transfer and black underneath to absorb heat and light.

  • Bulk contractor packaging. Special narrow roll width for ease of transport 
  • Free fall folded on piece cover for ease of application and does not require sealing or taping.
  • Enhanced puncture resistance and tear strength for superior performance and protection of moisture
  • 100% opacity and UV stabilised with 12 month UV warranty

Combi Vapour Layer

Donaghys' 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.

  • Users can save up to $5.50 per ton of silage*
  • Very low oxygen transmission rate, eliminating surface spoilage, saving time and money
  • Dry matter loss in the top metre of silage is reduced by 50%*
  • Aerobic stability is increased by up to 2.5 days so silage on face and in front of cows stays fresh and nutrient rich longer
  • Free fall configuration enabling underlayer and top cover to be easily deployed on pile in one action

* When compared to using a conventional black/white cover

Silage Underlayer

Originally designed as a secondary skin and protective layer in case of breakdown of the main silage cover, Donaghys' Underlayer is now intended to closely follow and adhere to the silage pit surface, preventing pockets of air forming and reducing spoilage. The vacuum film decreases the gas permeability and nitrogen oxide remains longer in the silo thus decreasing bacteria that can cause silage mould. The air seal also facilitates a faster more efficient fermentation process to deliver enhanced silage quality.

  • Acts as additional protection in case of damage to main sheet
  • Tough enough to withstand being walked on when it is being laid
  • Better recycling of the main sheet since it has no contact with fodder
  • Up to 25% less permeability of oxygen
  • Less permeability to all silage gases
  • Ideal for moist crops with greater potential for spoilage
