Polypropylene (PP) woven bags, also known as "snake skin bags", are high-performance packaging products made from premium polypropylene raw materials through extrusion, stretching, and warp-weft weaving processes. Combining light weight and high strength, they have a density of only 0.9-0.91 g/cm³, with a specific strength close to that of metal materials, enabling them to easily carry bulk goods while facilitating handling and transportation. Boasting excellent environmental adaptability, they are moisture-proof, stain-resistant, corrosion-resistant, and mold-free, effectively isolating moisture, dust, and odors to protect the contents from damage during storage and transportation. Economically priced, reusable, and recyclable, they significantly reduce packaging costs and align with sustainable development goals. Widely used in agriculture (grain, feed, chemical fertilizers), construction (cement, sand and gravel), chemical industry (plastic particles, industrial salts), food (rice, flour) and other fields, they are the ideal choice for industrial and agricultural production as well as logistics turnover.
