Engineering New Film Capabilities Through Nanolayer Architecture

Published on: Packaging Insights

This technical paper from Peak Nano describes how nanolayering can create unprecedented film performance at standard production cost. Rather than waiting years for new polymer chemistry to deliver incremental gains, Peak's NanoPlex™ technology coextrudes dozens to thousands of alternating nanoscale polymer layers, some as thin as 25 nanometers, to induce confinement-driven crystallization that produces structural film properties beyond what conventional layering or blending can achieve.

WHAT'S INSIDE:

• Why conventional multilayer film is capped by the rule of mixtures, and how nanolayer confinement effects break through that ceiling

• The NanoPlex layer multiplication (split-and-stack) coextrusion process, from feed block through sequential multiplier dies to finished film

• How confinement-induced crystallization reshapes polymer morphology, with parallels drawn from nacre, Morpho butterfly wings, and other layered structures found in nature

• Elimination of tie layers and adhesives in immiscible polymer systems, and the implications for recyclability and sustainable packaging

• The economics of retrofitting existing extrusion lines, and where nanolayering stands today: already deployed in dielectric capacitor films, and in active development for food and medical packaging
