Seam sealing is the application of a specialized waterproof film used to seal seams. Because sewing needles create small holes that will cause the fabric to leak, seam-sealing is used to seal the holes, to make the seam waterproof. Fully seam-sealed indicates that all seams are sealed, to make a watertight outer membrane.
