Eco-Friendly Waterborne Polyurethane Dispersion For Flexible Packaging Barrier Coating
Eco-Friendly Waterborne Polyurethane Dispersion is a high-performance colloidal system in which polyurethane polymers are stably dispersed in water, serving as an ideal raw material for flexible packaging barrier coatings. This Waterborne Polyurethane Dispersion exhibits excellent oxygen barrier properties due to its unique molecular structure, effectively blocking gas permeation and extending the shelf life of packaged contents. Furthermore, it functions as a robust anchoring and protective layer for deposited aluminum or alumina layers in high-barrier film structures, enhancing adhesion and preventing metal layer oxidation or degradation. Specifically designed for flexible packaging barrier coatings, this eco-friendly Waterborne Polyurethane Dispersion replaces traditional solvent-based systems, significantly reducing VOC emissions while maintaining superior coating performance, mechanical flexibility, and resistance to delamination.
