HEAT SEAL TESTER

Abstract: Aluminized composite film is a common barrier material for pharmaceutical packaging. Based on the principle of electrolytic sensor, this paper tests the water vapor transmission rate of three kinds of aluminized composite film samples for pharmaceutical packaging, compares their moisture barrier performance, and introduces the test principle, equipment parameters, applicable scope, test process, etc., which provides a reference for the test of water vapor transmittance of aluminized composite film samples. Keywords: aluminized composite film,
