Abstract
A liquid-impregnated flexible sheet includes high capillarity pores for retaining the impregnated fluid. The fluid may be an oil having a boiling point and vapor pressure sufficient to promote vaporization of the oil at room temperature. The vaporizable oil can function as a corrosion inhibitor making the sheet useful for wrapping metallic articles. A surfactant may also be added to the sheet to enhance corrosion inhibition. The sheet comprises a homogenous mixture of a polyolefin-based component and an inert filler. The sheet may be used alone or as one component of a composite that includes materials that have other desirable properties. The composite may be assembled into a container, such as a gun case.
