Inhibited mold and yeast growth
By limiting oxygen and moisture, covers prevent the growth of harmful microorganisms that degrade feed quality.
Enhanced fermentation
Stable anaerobic conditions support beneficial lactic acid bacteria, improving pH balance and digestibility.
Improved feed intake
Livestock prefer well-preserved silage, leading to better weight gain and milk production.
Advanced protection methods
Combining an oxygen barrier film with a durable black-and-green UV-resistant tarp and securing it with a silage net or tire weights maximizes protection and longevity.

Types of Silage Tarp
PE silage covers
Made from polyethylene (PE), these are the most widely used silage covers due to their cost-effectiveness and reliable performance. High-density or linear low-density polyethylene (HDPE/LLDPE) variants offer improved strength and puncture resistance.
Gas impermeable silage covers
Also known as oxygen-barrier or gas-retardant films, these advanced covers incorporate a thin ethylene vinyl alcohol (EVOH) or nylon layer that drastically reduces oxygen transmission, preserving forage freshness and reducing dry matter loss.
UV-stabilized silage covers
Engineered with UV-inhibiting additives, these covers resist degradation from prolonged sunlight exposure. They maintain structural integrity and protective function even in regions with intense solar radiation.
Multi-layer silage covers
Constructed with 2–3 co-extruded layers, these covers combine the benefits of different materials—such as a UV-resistant outer layer, a structural middle layer, and an oxygen-blocking inner layer—for maximum protection.
White plastic silage covers
Typically made from white-pigmented polyethylene, these covers reflect sunlight rather than absorbing it. This helps keep the silage cooler during hot weather, reducing the risk of overheating and secondary fermentation.
Green silage covers
Green-tinted covers are designed to block sunlight penetration while promoting heat retention. The color helps inhibit photosynthesis in residual plant material, reducing unwanted regrowth, while also aiding in warming the silage mass to accelerate fermentation.
