PROCESS FOR THE MANUFACTURE OF ORIENTED POLYMER STRIPS

摘要

A process for the manufacture of an oriented strip comprising a semi-crystalline polymer according to which a film comprising said polymer is drawn in a longitudinal direction on a length L between 2 points at which the film moves at a respective linear velocity of V1 and V2 during its drawing, characterized in that V1, v2 and L answer the following criteria: (v2-V1)/L > 0.22 s-1.
