Abstract:
1. A process for making a barrier assembly comprising: a) providing a flexible visible light-transmissive substrate having a Tg greater than or equal to that of HSPET; b) forming a first polymer layer having a Tg greater than or equal to that of HSPET atop the support; c) forming a visible light-transmissive first inorganic barrier layer atop the first polymer layer; d) forming a second polymer layer having a Tg greater than or equal to that of HSPET atop the first inorganic barrier layer; and e) forming a visible light-transmissive second inorganic barrier layer atop the second polymer layer wherein the barrier assembly has an oxygen transmission rate less than 0.005 cc/m
