Abstract
A method of monitoring stretchability of stretch films in a cast film method includes determining a position of a frost line of a film material, which is solidifying to form a film web, on a casting roller of a film machine, ascertaining a correlation of the determined position of the frost line with at least one target position, and comparing the ascertained correlation to at least one stretchability of the film material, which is assigned to the at least one target position.
