Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a cloudiness by incorporating a layer containing a first thermoplastic polyester and having at least one glass transition temperature (Tg), incorporating at least one type of crystallizing speed inhibitor, heating its total amount of a high Tg layer to a processing temperature exceeding the Tg, orienting it and then clarifying it. SOLUTION: In the case of heating a multilayer structure containing a composition having at least one low Tg layer and having a high Tg layer and at least one low Tg layer and orienting it, it can be strain-crystallized, strain- oriented, has excellent mechanical strength characteristics and no cloudiness and remains transparent as it is. These Tg layers (one or a plurality of layers) each contain a thermoplastic polyester and at least one type of crystallizing speed inhibitor. The inhibitor exists in an amount effective in the low Tg layer to prevent formation of a substantial cloudiness in the at least one low Tg layer in the case of heating the high Tg layer of the structure to a processing temperature exceeding the Tg of the high Tg layer.
