It can also affect the final cost, flexible packaging composite film factory is drunk

Film thickness uniformity gives the material has a certain protective function, let's do a barrier layer, for example, whether blocking layer uniform will directly affect the overall barrier performance of materials. General blocking layer thickness, the greater the blocking performance of thin film, the better, but the thickness of the barrier layer to a certain thickness, the blocking performance is stable, and no longer increases with the increase of the barrier layer thickness. And the high cost of high barrier material, so the thickness of the barrier layer directly affect the overall cost of the barrier property of composite membrane. In addition, if the thickness of the barrier layer of uneven prone to the function of the barrier layer is poorer, leading some packaging are blocking performance is poorer, the cause of any product shelf life, to cut off part of the thin film thickness changes will also affect the appearance of the film overall color, reduce the appearance of the goods. So if you want to avoid similar problems, we should be through the thickness of the test equipment to test the thickness of the composite membrane. Thickness detection devices have online thickness online thickness and the two kinds of equipment. Online thickness measurement equipment can with the fastest speed to obtain the thickness of the test data, and adjust the parameters of the production line to reduce the thickness of the material, reduce the driving time of production line, but need to match match with production line scanning frame, it has certain limitation, repeated use and the price of the equipment, operation and maintenance costs are much more expensive than the online thickness measurement equipment. Not cheap online thickness measurement device, small volume, easy to use, but the thickness is relatively slow. So each composite film factory can according to your own requirement and objective conditions to choose suitable thickness measurement equipment.
