Construction and sand bags are rugged, heavy-duty packaging solutions designed for transporting and containing abrasive materials like sand, cement, aggregates, gravel, and construction debris. Made from thick, high-density woven polypropylene, they offer exceptional puncture/tear resistance, high weight capacity, and the ability to endure rough construction site handling. Key features include UV inhibitors for prolonged outdoor exposure, plus optional loose weave (for water permeability in flood control) or reinforced stitching and high-grammage fabric (for industrial durability). As a professional China-based manufacturer, Dafeng Packaging produces bags optimized for reliability and operational efficiency.
