PURPOSE: A method for embossing a multi-layered film is provided to suppress the hardening of a film due to crystallization by excluding a secondary heating process and to form even embossed parts. CONSTITUTION: Resin materials having different deformation temperatures are supplied through a material input unit(10) and heated in a T-plate(20). The molten materials are discharged in the shape of a multi-layered film through a discharge outlet of the T-plate. The film is placed on a cooling… CONTINUE READING
