PROBLEM TO BE SOLVED: To provide a plastic sheet having foldable ruled lines using a lactic acid-based resin which is a plastic derived from a plant raw material, which has ruled line characteristics such as excellent ruled line processability and folding processability, and excellent heat resistance, impact resistance, transparency, sheet appearance, impact whitening resistance and stiffness (strength).SOLUTION: There is provided a plastic sheet having foldable ruled lines which is obtained by laminating a layer (X) which is mainly composed of a polycarbonate-based resin (A) and has a single glass transition temperature and a layer (Y) mainly composed of a lactic acid-based resin (B), wherein the absolute value of the difference between the melt viscosity (a shear rate of 1000 sec-1) of the layer (X) and the layer (Y) at 250°C is 100 Pa s or more and 1000 pa s or less.SELECTED DRAWING: None |
