It turns out that it can also affect the final cost of the flexible packaging compound film factory, and it is also drunk
The uniform thickness of the film gives the material a certain specific protection function. Below we take the barrier layer as an example to introduce. Whether the barrier layer is uniform will also directly affect the overall barrier performance of the material. Generally, the larger the thickness of the barrier layer, the better the barrier performance of the film, but after the thickness of the barrier layer reaches a certain thickness, the barrier performance tends to be stable, and will not increase with the increase of the thickness of the barrier layer. And the cost of high barrier materials is relatively high, so the thickness of the barrier layer directly affects the overall cost of the barrier composite film . In addition, if the thickness of the barrier layer is uneven, the function of the barrier layer is likely to be poor, resulting in poor barrier performance of some packaging materials, resulting in the product not reaching the expected shelf life, and the thickness of some film barrier layers will also affect the film. The overall appearance color reduces the appearance of the product.
So to avoid similar problems, we should use the thickness detection equipment to detect the thickness of the composite film . There are two types of thickness detection equipment: online thickness measurement equipment and non-online thickness measurement equipment. The online thickness measurement equipment can obtain the thickness test data at the fastest speed, and adjust the parameters of the production line in time to reduce the thickness fluctuation of the material and shorten the start-up time of the production line. Certain restrictions, and the price of equipment, operation and maintenance costs are more expensive than non-online thickness measurement equipment. Non-online thickness measurement equipment is cheap, small, and easy to use, but the thickness measurement speed is relatively slow. Therefore, each composite membrane factory can choose the thickness measurement equipment suitable for itself according to its own requirements and objective conditions.
