Vapor Seals

Protect Your Silage & Preserve Feed Quality


Feed Stuff Bagging offers high‑quality Vapor Seals designed to create a strong, airtight barrier beneath your bunker cover or pile cover. These heavy‑duty sheets help minimize oxygen infiltration, protect nutrient value, and support stable fermentation across a wide range of forage types.



Why Choose Our Vapor Seals

  • Excellent Oxygen Barrier Placed directly over the forage surface, Vapor Seals significantly reduce air movement — supporting ideal anaerobic conditions.
  • Heavy‑Duty Construction Durable film resists tearing, puncturing, and stretching when applied over uneven surfaces.
  • Improved Silage Quality Better seal = lower spoilage, improved top‑layer preservation, and reduced dry‑matter loss.
  • Easy to Install Lightweight compared to standard covers and designed to lay flat, conforming to the feed surface for a tight seal.
  • Pair With Any Bunker Cover Works perfectly beneath your primary white/black silage cover for an added layer of protection.
