摘要: The present invention provides a multiple layer structure (10) for fabricating medical products. The layer structure (10) has a core layer (14) of an ethylene vinyl alcohol copolymer having an ethylene content of about 25-45 mole percent, a solution contact layer of a polyolefin positioned on a first side of the core layer, an outer layer (12) positioned on a second side of the core layer opposite the solution contact layer (16), the outer layer (12) being selected from the group consisting of polyamides, polyesters and polyolefins; two tie layers (18)—one of each adhered to the first and second sides of the core layer (14) and positioned between the solution contact layer (16) and the core layer (14) and between the outer layer (12) and the core layer (14), and wherein the structure (10) is produced in a cast coextrusion process.
