6 Best White Tarps for Silage Protection

There’s nothing more frustrating than peeling back a silage tarp in late August to find a black, slimy, spoiled layer on top of the feed you worked all spring to grow. That top six inches represents a significant loss of time, fuel, and nutrients. Choosing the right cover, especially for summer, is one of the most critical decisions you’ll make for preserving your livestock’s winter rations.

Why White Tarps Excel in Summer Heat Conditions

The color of your silage tarp is more than just an aesthetic choice; it’s a critical tool for temperature management. Black tarps are excellent at absorbing solar radiation, which is the last thing you want baking on top of your fermenting feed pile during a heatwave. That absorbed heat penetrates the surface layers, raising the temperature of the silage.

Elevated temperatures can wreak havoc on the fermentation process. Heat encourages the growth of undesirable microbes like yeasts and molds, which thrive in warmer conditions and consume valuable nutrients. This not only reduces the feed value but can also lead to spoilage and potential health issues for your animals. A hot pile is an unstable pile, burning through the very energy and protein you’re trying to preserve.

A white tarp, on the other hand, reflects a huge percentage of that solar energy. This simple act of reflection keeps the surface of the silage significantly cooler, promoting a more stable and complete fermentation. For the smaller piles common on hobby farms, this effect is even more pronounced. With a higher surface-area-to-volume ratio, your pile is more vulnerable to external temperature swings, making a reflective white cover a non-negotiable piece of equipment for preserving feed quality through the summer.

Farm Plastic Supply: Top UV & Puncture Resistance

When you need a reliable, tough-as-nails cover, Farm Plastic Supply is a name that consistently delivers. They specialize in high-quality polyethylene films made from 100% virgin resins, which means you’re not getting recycled plastics that can have weak points or inconsistencies. Their tarps are built for the realities of farm life.

Their standard white/black silage tarps are a perfect example of smart design. The white outer layer reflects sunlight to keep the pile cool, while the black inner layer completely blocks light. This prevents any photosynthesis from occurring if a stray weed seed found its way into the pile, and it further protects the silage from light degradation. They also incorporate strong UV inhibitors, which is crucial for preventing the plastic from becoming brittle and cracking after months of sun exposure.

What really stands out is the puncture and tear resistance. You know you’ll be walking on the pile to place tires or sandbags, and there’s always the risk of a fallen branch or an animal trying to climb on it. A cheap tarp will tear easily, creating an entry point for oxygen and rain. The durability of these tarps means you can cover your pile with confidence, knowing it will maintain its integrity throughout the entire season.

Raven Dura-Skrim: Reinforced for High Durability

If you’ve ever had a tarp rip during a windstorm or while dragging it over the pile, you understand the value of reinforcement. Raven’s Dura-Skrim series takes durability to the next level by embedding a heavy-duty grid of polyester cord within the polyethylene layers. This scrim acts like rebar in concrete, dramatically increasing the tarp’s tear resistance.

This construction makes Dura-Skrim an excellent choice for high-stress applications. Think of covering a bunker with sharp corners, a pile with an uneven surface, or dealing with consistently high winds. Where a standard film might tear and run, the reinforced grid will stop the tear from propagating, often allowing for a simple patch job instead of a catastrophic failure.

Of course, this advanced durability comes at a higher cost. It’s a premium product, and you’re paying for the added security and potential for multi-season use. For a hobby farmer, this is a calculated investment. If you have a permanent bunker silo and can carefully remove, clean, and store the tarp, a Dura-Skrim cover could last several years, making the upfront cost more palatable over time.

Silostop Max: Ultimate Oxygen Barrier Technology

Silostop approaches silage protection from a different angle: it’s all about stopping oxygen. While a standard white tarp is a physical barrier, it’s still slightly permeable to oxygen molecules. Silostop introduces a two-step system that creates a near-perfect anaerobic environment.

The system uses a very thin, flexible oxygen barrier (OB) film that is laid directly on the silage surface before the main tarp goes on. This film is designed to cling to the contours of the pile, effectively eliminating the tiny air pockets that get trapped under a conventional cover. These air pockets are where spoilage begins. By removing them, you halt the growth of aerobic bacteria and molds right at the surface.

The main white/black protective tarp is then placed over the OB film to provide UV protection and physical durability. For a hobby farmer, this might seem like an extra, complicated step. However, if you’re ensiling high-value forage like alfalfa or high-moisture corn, the feed saved can be substantial. Reducing that top layer of spoilage from several inches down to almost nothing means more high-quality feed for your animals, easily justifying the cost of the extra film.

Tytan International: Reliable All-Purpose Coverage

Sometimes, you just need a solid, dependable product that gets the job done without any fuss. Tytan International has built a reputation for providing exactly that. Their white/black silage covers are the workhorses of the industry, offering a great balance of performance, durability, and cost.

Their films are known for their consistency and quality. When you buy a 5-mil Tytan tarp, you can be confident you’re getting a true 5-mil thickness with good UV protection that will last the season. There are no frills here, just a well-made product designed for its intended purpose: to protect your silage from sun, rain, and air.

This makes Tytan an ideal choice for the hobby farmer with standard needs. If you’re putting up a corn silage pile in the fall that you’ll feed out over the winter, this is a fantastic, cost-effective option. It provides all the essential protection—light reflection, a light barrier, and water resistance—at a price point that makes sense for smaller operations. It’s the reliable, all-purpose choice you can count on.

Global Plastic Sheeting: Custom Sizes for Any Pile

One of the biggest challenges on a small farm is that our infrastructure is rarely "standard." You might have a long, narrow trench silo you built yourself or an oddly shaped pile tucked into the corner of a field. Buying a standard-sized tarp often means you either have too little coverage or a massive amount of expensive, wasted plastic.

Global Plastic Sheeting solves this problem by offering custom-cut sizes. Instead of trying to tape two tarps together—a method that almost guarantees leaks and air infiltration at the seam—you can order a single, continuous sheet cut to the exact dimensions of your pile. This is a game-changer for anyone with a non-standard setup.

Eliminating seams is the single best way to improve the integrity of your silage cover. Seams are weak points that fail under stress from wind, water, and weight. By ordering a custom-sized tarp, you create a monolithic barrier that is far more effective at sealing out the elements and protecting your valuable feed. It saves you time during covering, reduces waste, and ultimately leads to better-preserved silage.

Bunker Cover USA: American-Made Silage Protection

For many farmers, knowing where their supplies come from matters. Bunker Cover USA distinguishes itself by offering high-quality, American-made silage protection products. This focus on domestic manufacturing often translates to reliable quality control and materials you can trust.

Their white/black silage covers are produced with a focus on durability and performance in demanding North American climates. They use top-grade resins and UV inhibitors designed to withstand intense summer sun without becoming brittle. The result is a tough, dependable tarp that holds up well against punctures and tears throughout the feeding season.

Choosing an American-made product can also have practical benefits beyond the tarp itself. It often means more accessible customer support and a more resilient supply chain. When you’re in a pinch during harvest and need to get a cover quickly, dealing with a domestic company can make a real difference. It’s an investment in a quality product and a robust agricultural supply network.

Key Factors: Tarp Thickness, Mil, and Lifespan

When comparing tarps, you’ll constantly see the term "mil." A mil is a unit of thickness equal to one-thousandth of an inch. It’s the primary way plastic sheeting is measured. A standard, single-season silage tarp is typically 5 mil, while a more heavy-duty or multi-season option might be 6 mil or higher.

While a higher mil count generally means greater strength and puncture resistance, the quality of the plastic is just as important. A 5-mil tarp made from 100% virgin resin with good UV inhibitors will almost always outperform a 6-mil tarp made from cheap, recycled plastics. Don’t let the number be your only guide; consider the manufacturer’s reputation and the material composition.

Ultimately, the choice comes down to a tradeoff between cost, labor, and intended lifespan. A less expensive 5-mil tarp is a single-use product; you’ll cover the pile and cut it off at the end of the season. A more expensive, reinforced, or thicker tarp might last two or more seasons if you’re willing to put in the effort to carefully remove, clean, and store it without causing damage. Match the tarp’s lifespan and durability to your specific needs and budget—there’s no single right answer for every farm.

Your silage cover isn’t just a piece of plastic; it’s insurance for your feed. By choosing a high-quality white tarp suited to your climate and pile, you’re actively preventing spoilage and protecting the nutritional value of your harvest. Making this decision thoughtfully before the chopper ever hits the field is one of the smartest investments you can make in your farm’s success.
