(57) 【Abstract】 PROBLEM TO BE SOLVED: To produce a container from an amorphous polyester (A-PET) sheet, in order to eliminate blocking and cutting difficulty of the sheet during transportation on a production line, polyester is used. On the other hand, by blending the inert particles and the aliphatic ester compound, the slipperiness of the sheet is improved without impairing the transparency. SOLUTION: Polyethylene terephthalate copolymerized with 1,4-cyclohexanedimethanol is blended with inert particles having a specific average particle diameter (eg, silica, calcium carbonate, etc.) and a long-chain aliphatic ester compound in specific amounts. As a skin layer, a polyester having an ethylene terephthalate unit as a main component as a core layer, a thickness of the skin layer, and a polyester multilayer sheet for setting the intrinsic viscosity of all layers in a specific range and processed from it. Polyester container. |
