Abstract

La presente invención se relaciona con un método para la producción de una tira de película multicapas de al menos dos tiras de película iniciales, de material polimérico termoplástico, cada tira de película inicial comprendiendo al menos un componente polimérico con punto de fusión bajo y al menos un componente polimérico con punto de fusión alto. El método comprende las siguientes etapas: producir de al menos dos tiras de película iniciales por medio de extrusión por soplado, extrusión por moldeo, o una combinación de extrusión por soplado y extrusión por moldeo; guiar de las al menos dos tiras de película iniciales juntas sobre al menos un cilindro de calefacción hasta el estado parcialmente fundido en el cual en cada tira de película inicial el al menos único componente polimérico con punto de fusión bajo se encuentre en estado fundido y el al menos único componente polimérico con punto de fusión alto en estado no fundido, y guiar de la tira de película multicapa, parcialmente fundida a través de una abertura entre cilindros refrigerada. La invención se relaciona además con la tira de película multicapa producida mediante el método, así como con el uso de la misma.
