Use of NANOSEAL™
Coatings to Create Clear, High-Barrier, Packaging Films
April 2010 |
| |
Summary
This document describes NanoSeal barrier coatings for packaging films and discusses the benefits (performance, economic and environmental) of using them in place of other optically-clear, barrier packaging materials.
Technology Overview
NanoSeal coatings are aqueous dispersions of vermiculite platelets in polyvinyl alcohol (PVOH). The platelets are 1-3 nanometers thick and 10-30 microns in breadth, yielding an average aspect ratio (breadth-to-thickness) of ~10,000:1. The platelets are maintained in singularized format when dispersed into the PVOH resin and aligned in the plane of the coating when deposited on a film substrate, such as polyethylene terephthalate (PET), biaxially oriented polypropylene (BOPP), biaxially oriented nylon (BON) or polylactic acid (PLA). The dispersed platelets create a tortuous path for gas molecules, enabling extraordinarily high gas barrier in a very thin layer (0.2 - 0.5 microns dry) with excellent bond strength, clarity and flexibility. The proprietary formulation also improves the moisture-resistance of the PVOH resin.

bond strength, clarity and flexibility. The proprietary formulation
also dramatically improves the moisture-resistance of the PVOH
