BOPP tape film thickness measurement is one of the basic inspection items for the film manufacturing industry. Some other performance indicators of the film are related to thickness. Obviously, if the thickness of a batch of single-layer film is not uniform, it will not only affect the tensile strength and barrier properties of the film, but also affect the subsequent processing of the film. For composite films, the uniformity of thickness is more important, only the overall thickness is uniform, and the thickness of each layer of resin may be uniform. Therefore, whether the thickness of the film is uniform, whether it is consistent with the preset value, and whether the thickness deviation is within a specified range, these are prerequisites for whether the film can have certain characteristic indexes.
Film thickness measurement is divided into online test and non-online test. The earliest film thickness measurement is off-line thickness measurement technology. Later, with the continuous development of ray technology, online thickness measuring equipment installed with the film production line was gradually developed. In the 1960s, online thickness measurement technology has been widely used, and now it is more able to detect the thickness of a certain coating of a film. On-line thickness measurement technology and non-online thickness measurement technology are completely different in the test principle. On-line thickness measurement technology generally adopts non-contact measurement method such as ray technology, and non-online thickness measurement technology generally adopts mechanical measurement method or based on eddy current technology or electromagnetic induction. The principle measurement method also uses optical thickness measurement technology and ultrasonic thickness measurement technology.
