The ISO 4591 standard specifies a method for determining the thickness of Plastic films and flakes. The weight method (weighing method) is used to determine the average thickness of the sample and the average thickness and yield of the roll. The method calculates the thickness of the film or sheet by accurately weighing the mass of the film or sheet, combined with the known material density. This method is suitable for thickness measurement of different types of Plastic films and flakes and can provide high-precision data to help evaluate the uniformity of the material and the thickness fluctuations that may exist during production. The standard provides an important technical basis for the quality control and production management of Plastic films.
