Product Details
Introduction
Utilizing state-of-the-art 5-layer co-extrusion technology, our production facilities enable us to manufacture high-performance grain storage sleeves that meet the most demanding agricultural standards. As a trusted innovator in crop preservation solutions, we offer an efficient and reliable alternative to traditional grain storage methods such as silos and warehouses.
Our grain sleeves significantly reduce initial investment costs while providing the flexibility to store and organize grain directly on your farm. This approach enhances logistical efficiency, supports better crop management, and ensures your harvest remains protected under optimal conditions—all within the convenience of your own operation.
Benefits
 |
All-Weather DurabilityOur grain storage sleeves are manufactured using advanced multi-layer co-extrusion technology ( 5-layer or 7-layer), available in a variety of color combinations including black/white, green/white, black/green, and solid black—each designed to deliver superior environmental protection and light-blocking performance throughout the year. |
 |
Enhanced UV & Thermal ResistanceWe incorporate high-efficiency UV inhibitors and anti-oxidant stabilizers into our material composition, ensuring reliable long-term performance and resistance to degradation—even under extreme weather and continuous sun exposure. |
 |
Reinforced Material IntegrityA proprietary blend of polymers gives our bags exceptional puncture and tear resistance, significantly reducing the risk of ruptures during filling, storage, or transport. This results in stronger, more dependable grain protection. |
 |
Lowest Storage Cost with Maximum FlexibilityWith on-site storage capabilities and no need for expensive silos or buildings, our solution dramatically reduces upfront investment and operating expenses. Enjoy efficient loading and retrieval while maintaining grain quality right on your farm. |

Things You Need To Know
What exactly are grain/silage bags?
Grain and silage bags are large, heavy-duty polyethylene tubes (typically 6-12+ feet in diameter and 100-300+ feet long) designed for hermetic (airtight) storage of harvested grains (like corn, wheat, soybeans) or fermented feed (silage, haylage, high-moisture corn). They provide a flexible, cost-effective alternative to traditional silos or bins.
What are the MAIN benefits of using bags vs. traditional storage?
Lower upfront cost: Significantly cheaper than building bins or silos.
Flexibility & Scalability: Store different commodities, adjust volume year-to-year, use in various locations.
Hermetic Seal: Excludes oxygen, preventing spoilage, mold growth, insect infestation, and preserving nutritional value (especially crucial for silage).
Reduced Waste: Minimizes dry matter losses compared to open piles or poorly sealed structures.
Speed: Faster to fill than many fixed structures.
How long can grain/silage be stored in the bags?
Grain: Properly sealed dry grain can often be stored for 12-18 months, sometimes longer, depending on initial moisture content, temperature, and bag quality.
Silage/Haylage: Designed for the entire feeding season (typically 6-12 months). Once opened, feed out should be relatively quick.
Key Factor: Integrity of the seal and absence of punctures are critical for maximum storage life.
How durable are the bags? Can they withstand weather and animals?
Our bags are made from multi-layer, UV-stabilized polyethylene for superior strength and weather resistance (sun, rain, wind).
They are puncture-resistant, but physical damage is the biggest risk. Protection from:
Rodents: Use bait stations/traps around the perimeter.
Birds: Deterrents are helpful.
Machinery: Be extremely careful during filling, inspection, and feed-out. Avoid driving near them.
Sharp Objects: Clear the site thoroughly before laying the bag.
What moisture content is safe for bagging?
Grain: Must be dried to a safe, stable moisture level before bagging (e.g., corn <15%, wheat <13.5%). Bagging wet grain leads to spoilage.
Silage/Haylage: Requires adequate moisture for proper fermentation (typically 50-65% moisture). Too dry prevents fermentation; too wet causes undesirable fermentation and effluent seepage. Consult specific recommendations for your crop.
How do I unload the silage/grain?
Silage: Use a specialized bag loader (face shaver) that cuts a controlled opening across the width of the bag and removes silage in layers.
Grain: Can be unloaded using a grain vacuum, specialized bag unloader, or by carefully cutting an opening and using a front-end loader (take extreme care not to puncture the bag further). Always start at the sealed end opposite the filling end.
What happens if the bag gets punctured?
Repair Immediately! Use high-quality, UV-resistant polyethylene repair tape specifically designed for silage/grain bags. Clean and dry the area around the puncture thoroughly before applying the tape, ensuring a complete seal over the hole. Small punctures repaired quickly minimize losses.
How much does it cost per ton/bushel to store in bags?
Costs include the bag itself, bagger rental/operation, site prep, and labor. Generally, it's very cost-effective compared to building permanent storage. The cost per ton decreases significantly with larger bag sizes and volumes stored. Contact us for a specific calculation based on your needs.
