PRESSURE SENSITIVE VALVE SYSTEM AND PROCESS FOR FORMING SAID SYSTEM

摘要

A thin elastomeric polymeric sheet material having at least about 100 valves per square inch is disclosed. In some embodiments the valves are microvalves where the maximum functional aperture of each of the microvalves generally ranges from greater than about 10 square micrometers to less than about 100,000 square micrometers. Also disclosed is a one-way valve system.
