Barrier Film
Sangbo provides Industry's Best Performance
Product: Barrier Films

Introduction

Sangbo’s Barrier Film utilizes advanced Wet technology to maximize moisture barrier performance.

With a roll-to-roll wet coating process, it enables uniform coating over large areas while maintaining high optical transparency (≥90%).

Features

Excellent Moisture Barrier Performance

WVTR (Water Vapor Transmission Rate) < 10⁻⁴ g/m²·day

High Optical Transparency

Light Transmittance ≥ 90%

Enhanced Flexibility and Crack Resistance

Achieved through the use of organic–inorganic hybrid materials for superior mechanical flexibility

High Thermal and Humidity Stability

Ensured by the application of additives optimized for heat and moisture resistance

Roll-to-Roll Mass Production

Wet coating process provides superior cost efficiency compared to vacuum deposition methods (CVD, PVD)
