One of the most common problems garment factories face today is this: The seam looks perfect on the production line,but fails after washing. The tape peels off.The seam leaks.The garment fails inspection. When this happens, factories often assume: the fabric is the problem, or the seam tape quality is not strong enough. In reality, most seam sealing failures after washing are caused by system mismatch, not by the tape or fabric alone.
