As the application of functional optical films becomes more widespread, a multi-layered transparent film composed of a plurality of optical films is also widely used. Under the lamination of multiple layers, a colloid is required between the layers for bonding. Interface. Conventional techniques are used in the production of multi-layered light-transmissive films by conventional thermal lamination. For example, in order to complete a three-layer multi-layer film, it is necessary to complete the basic curing process through a bonding curing device. The first and second film layers are laminated and adhered, and then the composite film layer which has completed the first lamination bonding and the adhesive layer is again fed into the bonding curing device to be performed on the previously completed double-layer film. The third layer of the superposition adhesive and the adhesive layer are cured to complete the three-layered multilayer film.

The conventional manufacturing method not only has to consume a considerable amount of time and cost to repeatedly carry out a layer of laminated film layers, but also the film layer which has undergone multiple curing processes is prone to problems such as qualitative change, and further, the film layer is produced.
