Mono-Material Structures Displace Polyester With Oriented Polypropylene
European Packaging and Packaging Waste Regulation recyclability requirements pushed brand owners toward laminates built entirely from one polymer family. Every such structure needs a layer far stiffer than the sealant to provide pack body, print registration and machinability, and polyester had always supplied it. Machine direction oriented polypropylene delivers comparable stiffness while keeping the structure within a single recycling stream. The segment compounds at 12.5% against a market at 8.3%, and each conversion displaces a polyester layer permanently rather than temporarily. Polyester loses that layer for good. Recyclability created a role that did not exist.
Market Impact: Thickness reduced 34% at equal stif
