How to Choose High-Sealing Bulk Bags for Packaging Pesticides and Mineral Powders?

In the packaging of fine powders such as pesticide ingredients and minerals, sealing performance, structural strength, and safety are top concerns. These materials are typically fine-grained and free-flowing, and any leakage due to poor packaging can lead to dust pollution, environmental risks, and regulatory violations. Therefore, selecting a high-sealing FIBC bulk bag is essential for secure shipment.

Circular big bags, with their seamless tubular design, eliminate side seam leakage problems found in traditional four-panel bags. Optional PE liners can be added to further enhance dust control and moisture resistance. Made from 100% virgin polypropylene, these bags offer excellent chemical resistance, ensuring safe contact with pesticides or mineral compounds.

Structurally, the bags feature 3-inch wide cross-corner lifting loops with full belted reinforcement, supporting loads up to 2000 kg—ideal for bulk shipments in mining and chemical industries. The combination of a filling spout on top and a star-petal or iris discharge spout at the bottom allows for clean, controlled filling and discharging, minimizing secondary dust exposure.

For pesticide manufacturers, mining companies, and powder processors, using high-sealing circular FIBC bags ensures safe operations, regulatory compliance, and improved packaging efficiency.
