摘要:
The present invention relates to a process for manufacturing a transparent article with gas-barrier properties by coextrusion blow-molding, the said article comprising at least a structure of the type: layer of EVOH/tie layer/layer of glycolised copolyester and relates to a multilayer structure comprising a coextrusion tie layer adhering to a layer of glycolised polyester copolymer. The said tie comprises a blend of metallocene polyethylene, non-metallocene LLDPE, both of which are co-grafted, and non-grafted polyethylene. The invention also relates to articles comprising such a structure, in particular hollow bodies.
