<p>PROBLEM TO BE SOLVED: To obtain the subject packing container excellent in transparency by using a thermoformable polyester resin composition excellent in transparency, impact resistance, and heat resistance. SOLUTION: This sheet-like formed product comprises a polyester resin composition obtained by compounding (A) 99.5-50 wt.% aromatic polyester and (B) 50-0.5 wt.% polyester block copolymer, has <=5% scattered quantity of light (haze) and >=200% tensile elongation at break, and can be subjected to thermoforming. The polyester block copolymer B consists of a block (a) consisting of an aromatic polyester having a crystallinity with >=200 deg.C melting point singly, and a block (b) consisting of a polyoxyalkylene glycol having <=1,000 molecular weight, and contains 5-30 wt.% block (b) based on the amount of the block copolymer B.</p> |
