Parallel Bottom Dual Lifting Loops Bulk Bag

Our Parallel Bottom Dual Lifting Loop Bulk Bag is an industrial-grade FIBC designed for heavy bulk materials. Its core advantage lies in its exceptional structural strength: the unique parallel bottom support structure evenly distributes weight across the bag's bottom and lifting loops, reinforced with two strengthening bands. This effectively prevents the "hourglass effect" common in traditional bulk bags during hoisting, significantly reducing the risk of bag breakage caused by material accumulation at the bottom. It offers a standard load capacity of 1–2 tons.

In terms of material wear resistance, the bag body is made of high-strength polypropylene (PP) or polyethylene (PE) woven fabric, with a special coating or lamination on the surface. This not only provides UV resistance, moisture protection, and dust prevention but also significantly enhances tear and abrasion resistance, ensuring long-lasting durability under frequent handling, long-distance transportation, and stacked storage.

The product also excels in reusability. Its durable materials and reinforced design support multiple cycles of use, far exceeding the lifespan of disposable packaging. When empty, the bag can be folded compactly, minimizing storage and transportation costs. This design balances the economic benefits of high-volume loading with environmental sustainability, making it a safe, efficient, and eco-friendly transportation solution for industries such as building materials, mining, chemicals, and grains.

Structural Design

 

The bottom utilizes high-strength woven straps arranged in a crisscross pattern to form a "three-dimensional grid structure" support system. This design evenly distributes load pressure across each grid unit, with reinforced emphasis on vulnerable areas such as the bottom corners and the junctions with lifting straps. Laboratory simulation tests show that the compressive strength of a single-layer grid is approximately 40% higher than that of traditional flat-bottom designs, effectively preventing deformation or damage caused by localized stress concentration.

Exceptional Load-Bearing Capacity

 

Specifically designed for long-term storage of high-density powdered materials such as cement, mineral powder, and metallurgical powders. The grid structure maintains its three-dimensional supportive form even under fully loaded conditions. Even in multi-layer stacking scenarios (recommended ≤ 3 layers), it effectively resists lateral pressure from material settling, ensuring stack stability and preventing bag collapse or toppling.

Application Scenarios

 

Widely used in the sealed packaging of powdered and granular materials across industries such as building materials, metallurgy, and chemicals. It offers excellent sealing performance for dust-prone materials like cement and quartz sand. For chemically corrosive raw materials, its durable structure, combined with optional inner liners, ensures high stability and safety during storage and transportation, meeting the demands of harsh industrial environments.
