Brand Family Overview

VaporCoat® recyclable water-based coatings confer high barrier to paper-based packaging and wraps. Most VaporCoat grades are designed for “low MVTR”, to retard water vapor transmission in order to keep perishables fresh, frozen goods intact, or sensitive contents in factory condition. In response to market interest for greater food safety and preservation, additional VaporCoat products can inhibit contaminants ordinarily found in recycled paper from migrating into packaged dry food.

This sizing polymer provides exceptionally tight particle size control for fiberglass and other fibers used to reinforce polypropylene. It provides excellent strand integrity in chopped strand applications and contributes to great mechanical properties in the final composite. It is characterized by its small and very consistent mean particle size. As a binder it provides block resistance for soft goods. This product is APE free.
