Abstract
A process of making a protective composite wrap, which exhibits the ability to protect metallic objects from corrosion environments, wherein a first thermoplastic resin and a vapor corrosion inhibitor are blended into a homogenous blend, wherein the homogenous blend is extruded into continuous thermoplastic filaments, which are collected into a nonwoven fabric, wherein a second thermoplastic resin is extruded into a continuous thin film, and wherein the nonwoven fabric and the thin film are affixed into a face to face juxtaposition to form the protective composite wrap.

A process of making a protective composite wrap, comprising:
- a. providing a thermoplastic resin;
- b. providing a vapor corrosion inhibitor;
- c. blending said thermoplastic resin and said vapor corrosion inhibitor into a homogeneous blend;
- d. extrude said homogeneous blend as continuous thermoplastic filaments;
- e. collecting and consolidating said thermoplastic filaments into a nonwoven fabric;
- and
- f. said nonwoven fabric exhibiting the ability to protect metallic objects from corrosion environments.
