PVC Dry Bags: Material, Welding & Applications

PVC dry bags use polyvinyl chloride film or coated fabric, welded with high-frequency (HF/RF) seams. PVC is rugged, puncture-resistant and the most cost-effective waterproof dry bag material, which is why it dominates high-volume and promotional dry bag orders.
