<p>A chemical is applied to a substrate in discrete areas, and then the substrate is folded in such a manner as to cause the discrete chemical areas to become interior surfaces after folding to reduce or eliminate chemical residues when the exterior surfaces of the substrate contact other surfaces or objects. By applying the chemical to discrete areas of the substrate, degradation or delamination of the substrate can also be minimized or reduced. Additionally, by including either a chemical free edge strip, a chemical free fold strip, or both further improvements in dispensing, preventing delamination, or reduced residue transfer are possible.</p> |
