    Test method Cosmetics packaging materials (film or sheet) thickness is uniform, is the basis for testing the performance of the film. Film thickness is not uniform, not only will affect the film around the tensile strength, barrier, etc., will affect the follow-up processing thickness of the film there are many ways, generally divided into non-contact and contact: non-contact Including radiation, eddy current, ultrasonic and so on; contact industry is also known as mechanical thickness measurement, divided into point contact with the surface contact. At present, the laboratory testing of the thickness of the cosmetic film adopts the mechanical surface contact test method, this method is also used as the thickness of the arbitration method.http://www.jintepackaging.com/
