Beschreibung
Zusammenfassung:	A process for producing a laminate in a coating line including the subsequent steps of: -providing a metal strip; -pre-heating the metal strip to a temperature of at least 100° C.; -producing a laminate by adhering a first thermoplastic polymer coating layer on one major surface of the strip and a second thermoplastic polymer coating layer on the other major surface of the strip wherein the first thermoplastic polymer coating layer includes a polymer with a melting point below 200° C.; -heating the laminate in a non-oxidising gas atmosphere in a post-heating step to at least the melting point of the polymer or polymers in the second polymer coating layer, and at least 220° C.; -rapidly cooling or quenching the laminate to a temperature of below 50° C. Also, a polymer coated metal strip produced thereby, or a can produced therefrom.
