Multilayer protective cover including nonwoven material

A method of making a protective cover, the method comprising:

• forming a composite sheet by
• providing a substrate formed from a nonwoven material, the substrate having a first surface and a second surface opposite the first surface, wherein the nonwoven material has a puncture resistance exceeding 500 N;
• disposing a first layer of plastic film on the substrate first surface, wherein the first layer of plastic film has a first thickness;
• disposing a second layer of plastic film on the substrate second surface, wherein the second layer of plastic film has a second thickness that is greater than the first thickness, and wherein the second layer of plastic film has a third surface in facing opposition with the substrate second surface and a fourth surface opposite the third surface;
• and
• disposing at least one third layer of plastic film on the fourth surface of the second layer of plastic film, wherein the at least one third layer of plastic film has a third thickness that is greater than the first and second thicknesses, and wherein the at least one third layer of plastic film has a fifth surface in facing opposition with the fourth surface of the second layer of plastic film, the at least one third layer of plastic film defining a smaller surface area than the second layer of plastic film;
• wherein the composite sheet has a first end, a second end, a first lateral edge extending between the first and the second end, a second lateral edge extending between the first end and the second end, and an axis extending between the first lateral edge and the second lateral edge;
• folding the composite sheet about the axis such that the first end of the composite sheet is proximate the second end of the composite sheet;
• securing the portion of the composite sheet extending between the first end and the axis to the portion of the composite sheet extending between the second end and the axis to define a partially enclosed space having an opening proximate the first and second ends of the composite sheet.

• folding the composite sheet about the axis to align the first end of the composite sheet with the second end of the composite sheet and define a partially enclosed space having an opening proximate the first and second ends of the composite sheet.
