Multilayer structure based on polyamide usable as a card

Abstract

The present invention relates to a multilayer structure based on polyamide for use as a card. This invention relates to a multilayer structure comprising: - an outer layer - a binder layer - an intermediate layer - a binder layer - a central layer - a binder layer - an intermediate layer - a binder layer - an outer layer. The compositions constituting the outer layers, intermediate layers, and central layer are made of a composition comprising a polyamide matrix and having a melting point above 150°C, preferably above 160°C, and the binder layers are made of a composition comprising a reactive functional polyolefin. The invention also relates to a method for manufacturing the structure and its use as a data card.
