To provide a multi-layer polyester sheet which shows high heat resistance and impact resistance and superb container moldability, and a molding using this sheet.
This multi-layer polyester sheet is of such a multi-layer structure that a surface layer consists of 92-98 wt.% of PET resin with a proper viscosity of 0.70 dl/g or more and 2-8 wt.% of polyolefin resin, and at least, one layer of an intermediate layer consists of 95 wt.% or less of a PET resin with a proper viscosity of 0.70 dl/g or more, 0.3-5 wt.% of polyolefin resin and 5 wt.% or more of non-crystalline resin. In addition, the multi-layer polyester sheet shows a degree of heat shrinkage of 2-8% as measured by the JIS method K 6734. The multi-layer polyester molding is obtained by molding the sheet and shows 10-40% crystallization of the surface layer.
