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.

Abstract: A corrosive gas resistant laminate comprises an outer polymer layer desirably containing a volatile corrosion inhibitor therein, a corrosion gas resistant barrier layer that can be a hydrophilic polymer, and a tie layer located between said outer and said barrier layers. The various laminates have improved transmission resistance with regard to corrosive gases such as oxygen, hydrogen sulfide, and halogen gases such as chlorine. The laminates can be used to protect metal during storage and transit.

Abstract: The present invention relates to biodegradable polymers which can be combined with, impregnated with and/or encapsulate one or more inhibiting formulas. More particularly, in one embodiment the present invention relates to a biodegradable polyester polymer which has been combined with, impregnated with and/or encapsulates one or more inhibiting formulas. This polymer composition can then be further processed into any suitable article. In another embodiment, the present invention relates to a biodegradable polyester polymer which has been combined with, impregnated with and/or encapsulates a desired amount of one or more tarnish and/or corrosion inhibiting formulas. In another embodiment, the one or more tarnish and/or corrosion inhibiting formulas can be dispersed within and through a suitable biodegradable polymer film.

Abstract: The present invention relates to corrosion inhibiting formulas. More particularly, in one embodiment the present invention relates to corrosion inhibiting formulas which comprise a mixture of: (i) at least one volatile corrosion inhibitor (VCI); (ii) at least one antioxidant; (iii) at least one alkali or alkaline-earth metal silicate or oxide; and (iv) fumed silica. In another embodiment, the present invention relates to corrosion inhibiting formulas which comprise a mixture of: (i) at least one volatile corrosion inhibitor (VCI); (ii) at least one antioxidant; (iii) at least one alkali or alkaline-earth metal silicate or oxide; (iv) fumed silica; and (v) at least one chemically active compound. Both of the mixtures described above can further include additional additives. In yet another embodiment, the corrosion inhibiting formulas according to the present invention can be placed in any suitable polymer film and/or polymer article.

Abstract: The present invention relates to tarnish inhibiting formulas. More particularly, in one embodiment the present invention relates to tarnish inhibiting formulas which comprise a mixture of: (i) at least one carrier; (ii) at least one strong alkali compound; and (iii) at least one compound which yields an insoluble compound. These mixtures can further include one or more additional additives such as antioxidants, corrosion inhibitors, etc. In yet another embodiment, the tarnish inhibiting formulas (and in some cases corrosion inhibiting as well) according to the present invention can be placed in a suitable polymer film and/or polymer article.
