The invention discloses a composite thermoplastic film and a manufacturing method thereof. The manufacturing method comprises the following steps: providing a first structural layer and a second structural layer; performing a co-extrusion step to form a composite layer, the co-extrusion step comprising: performing the co-extrusion step on the first structural layer by using a first extruder, so that the first structural layer is divided into a first hot melt adhesive film and a third hot melt adhesive film after passing through the first extruder, and performing the co-extrusion step on the second structural layer by using a second extruder, so as to form the composite layer, the second structure layer forms a second hot melt adhesive film after passing through the second extruder, and the second hot melt adhesive film is arranged between the first hot melt adhesive film and the third hot melt adhesive film, so that the first hot melt adhesive film, the second hot melt adhesive film and the third hot melt adhesive film form a composite layer; and executing a film forming step: cooling the composite layer into a film by using a forming wheel, and controlling the rotating speed of the forming wheel to obtain the composite thermoplastic film with the required thickness, and the composite thermoplastic film can be applied to a vacuum forming material.

    一种复合式热可塑性膜及其制造方法,包括:提供第一结构层及第二结构层;执行共挤出步骤以形成复合层,共挤出步骤包括:利用第一押出机对第一结构层执行共挤出步骤,使得第一结构层在经过第一押出机之后分流成第一热熔胶膜及第三热熔胶膜、及利用第二押出机对第二结构层执行共挤出步骤,使得第二结构层在经过第二押出机之后形成第二热熔胶膜,且设置在第一热熔胶膜及第三热熔胶膜之间,据此,第一热熔胶膜、第二热熔胶膜及第三热熔胶膜形成复合层;及执行成膜步骤,利用成型轮将复合层冷却成膜,且控制成型轮的转速以得到所需厚度的复合式热可塑性膜,此复合式热可塑性膜可应用于真空成型材料。
