ABSTRACT:
A multi-layered sheet material for wrapping metal goods to protect them from corrosion during storage has a water impermeable and water vapor-impermeable outer layer comprising a coated woven scrim and a water-impermeable and water vapor permeable inner layer comprising a micro-perforated film. The inner layer incorporates corrosion inhibitors. The outer and inner layers are bonded along their longitudinal edges leaving a space between the layers into which water vapor can migrate away from the wrapped metal product.
