Packaging test - Test methods for packaging films - Part 4: Determination of the shrinkage of plastic films in a liquid bath
Verpackungsprüfung - Prüfverfahren für Verpackungsfolien - Teil 4: Bestimmung der Schrumpfung von Kunststoff-Folien im Flüssigkeitsbad
Overview
DIN 55543-4 specifies a method for determining the shrinkage of plastic films in a liquid bath. Material orientation occurs during the production of packaging films. These affect the quality of the film and the weld seams. These material orientations lead to shrinkage when subsequently exposed to heat above the crystallite melting temperature. The degree of material orientation is determined by measuring the shrinkage.
