Composition of a radiation reflecting breather membrane

摘要

Composition of a radiation reflecting breather membrane, characterized in that it consists of two composed layer packages, respectively an outer layer package (1) nd an inner layer package (2), which are fused, whereby the outer layer package (1) comprises a monolithic polyethylene (PE) layer (4) and a metallic or metalized radiation reflecting layer (3) on the outside and a substrate layer (5) on the inside, whereby this outer layer package (1) is perforated, and whereby the inner layer package (2) comprises a monolithic layer (7) with a thickness (A) of less than 100 micrometer of extruded thermoplastic polyurethane (TPU) or thermoplastic polyester-ether (TPEE) fused to the substrate layer (5) of the aforementioned perforated outer layer package (1).
