Optical sorting rejection turns a finish into a liability
Material recovery facilities use near-infrared detection to sort polymers, and a metal layer defeats it, causing roughly 89% of metallized structures to be rejected into residue regardless of the base polymer beneath. That was an environmental footnote until producer responsibility schemes attached fees to unrecyclable packaging and brand owners published recyclability commitments. The finish that creates the entire commercial value of this category is now precisely the property that makes the pack fail, which is an uncomfortable position for any material. Neither fees nor brand commitments can be answered by improving the finish itself.
