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.

摘要翻译： 一种多层层叠膜的制造方法，其特征在于，将第一透明膜和水分率为0.5重量％〜5重量％的第二透明膜层叠水分率为10重量％〜60重量％的树脂膜 通过粘合剂或压敏粘合剂层粘合到树脂膜的两面上的重量％ 其中所述层压包括以下步骤：使所述树脂膜和所述第一透明膜在一对第一金属辊和第一弹性辊之间，使得所述第一透明膜被放置在所述第一金属辊侧，使得它们是 在压力下彼此粘合以形成层压膜; 然后使用层叠膜，不会卷起并使层压膜和第二透明膜在一对第二金属辊和第二弹性辊之间，使得第二透明膜被放置在第二金属辊上 使得它们在压力下彼此粘合以形成多层层压膜。 该方法可以防止在树脂膜和透明膜之间形成气泡。
