Abstract

An all-purpose plastic laminate or wrap as for preserving food that resists penetration of fluids such as water and gases such as oxygen, hydrogen sulfide, sulfur dioxide, and the like. The laminate includes many different embodiments such as at least one hydrophobic outer layer that is free of any volatile corrosion inhibitors, at least one gas resistant barrier layer that can be a hydrophilic polymer, and at least one hydrophobic inner layer that contains a desired additive such as a food safe preservative or antioxidant therein. Optionally at least one tie layer is located between the outer and/or inner layer and said fluid resistant barrier layer. The laminate when applied as a wrap to a food item provides synergistic protection against fluid penetration.
