A high-density waterproof coating is thermally laminated onto the outer surface of PP woven fabric, tightly bonded without peeling or flaking, delivering dense water barrier performance. Water beads roll off the fabric surface without permeation.
The double-layer composite structure combines the tensile strength and wear resistance of woven cloth with the rainproof water-blocking capability of coating. Superior to ordinary inner liners, it suits outdoor exposure to direct rainfall. The fabric is UV-resistant and anti-aging under sunlight, free of cracking after prolonged outdoor exposure.
All stitching holes on the bag are sealed with waterproof adhesive strips to stop water seepage through seams. Lightweight and easy to fold for empty storage. It can be used with inner liners for ultra double waterproofing, or used alone to cut packaging costs.
