    摘要： A method of preparing a multi-layer assembly, or of protecting a surface of a multi-layer substrate from damage and/or contamination and/or debris, said method comprising the steps of: (i) providing a composite film comprising a polymeric base layer having a first and second surface and disposed on the first surface thereof a polymeric protective layer having a first surface and a second surface such that the first surface of the said base layer is in contact with the first surface of the polymeric protective layer, wherein said polymeric protective layer comprises an ethylene-based copolymer, and preferably wherein the polymeric base layer comprises a polyester derived from one or more diol(s) and one or more dicarboxylic acid(s); (ii) removing said polymeric protective layer from the first surface of said base layer; (iii) disposing on the exposed first surface of said base layer one or more functional layers to provide a multi-layer substrate, wherein the, or at least the uppermost, functional layer comprises zinc and/or tin in an amount of from about 5 to about 80 wt% of said functional layer; and (iv) disposing a polymeric protective layer comprising an ethylene-based copolymer onto the exposed surface of the, or at least the uppermost, functional layer comprising zinc and/or tin to provide a multi-layer assembly.
