摘要:
A method for producing a multilayer laminated film comprising: laminating a resin film having a moisture percentage of 10% by weight to 60% by weight with a first transparent film and a second transparent film each having a moisture percentage of 0.5% by weight to 5% by weight to be bonded to both sides of the resin film through an adhesive or pressure-sensitive adhesive layer interposed therebetween; wherein the laminating comprising steps of: passing the resin film and the first transparent film between a pair of a first metal roll and a first elastic roll in such a manner that the first transparent film is placed on the first metal roll side so that they are bonded to each other under pressure to form a laminated film; and then, using the laminated film without winding up it and passing the laminated film and the second transparent film between a pair of a second metal roll and a second elastic roll in such a manner that the second transparent film is placed on the second metal roll side so that they are bonded to each other under pressure to form a multilayer laminated film. The method can prevent bubbles from being formed between the resin film and the transparent film.
