In Film cast extrusion, is there any relationship between die width and thickness of the film?

06 April 2021 1 8K Report

Thermoplastic elastomer film extrusion with very low thickness (50-100µm).

The die system is the heart of extrusion or co-extrusion of films and there is a relation between the width of the die & the thickness of the film emerging by casting.
