Personal Care Brands Rapidly Adopt Barrier Formats
Premium personal care brands pursuing active-ingredient protection and shelf differentiation are increasingly specifying multi-layer blow molded containers with documented oxygen transmission and layer adhesion testing, rather than the conventional single-layer container that dominated personal care packaging when co-extrusion molding costs were less competitive in prior years. This shift commands meaningfully higher unit cost than conventional single-layer format given the enhanced barrier and testing requirements involved. Converters report multi-layer orders now outpacing single-layer orders across several major personal care brand accounts tracked this cycle, a clear reversal from just a few years earlier across comparable launches.
