Abstract
Procedimiento para la fabricación de una película de plástico, comprendiendo el procedimiento extrusionar una película de plástico (5) y orientarla, caracterizado porque con anterioridad a la mezcla del material de extrusión en el plástico (5a) de la película de plástico (5), se forman burbujas de cavitación en el plástico (5) que se va a estirar debido a la influencia del material, después de la extrusión la película de plástico (5) es orientada mediante estirado, y simultáneamente con gas presurizado de orientación se dispone para su actuación sobre la película de plástico (5) de manera que el gas se propaga en las burbujas de cavitación, formándose de este modo las burbujas (25) que contienen gas en la película de plástico (5).
