Geo Fresh GF-RB7WB oxygen barrier is a 7 mil, ten-layer reinforced extrusion laminate. The outer layers are produced with high-strength polyethylene resins along with EVOH barrier resin extruded into one of the layers to provide an ultra-low oxygen transmision rate. The outer layers include carbon black (black side) and UV stabilizers (white side) to increase outdoor longevity. Geo Fresh GF-RB7WB is reinforced with a 1000 denier scrim laid in a diagonal pattern spaced 3/8˝ apart with an additional machine direction scrim every 9˝ across the width.
