<P>PROBLEM TO BE SOLVED: To obtain a laminated sheet for thermoforming having excellent heat resistance and thermoforming characteristics and achieving good rigidity of a formed container body obtained. <P>SOLUTION: The laminated sheet for thermoforming comprises two layers comprising a base material constituted of a thermoplastic and a biaxially-stretched polyester film. As the biaxially-stretched polyester film, an OPBT-based film having well-balanced film properties and comprising either of polybutylene terephthalate resin or a polyester-based resin composition obtained by compounding 30 wt.% or less of polyethylene terephthalate resin into polybutylene terephthalate resin is used. <P>COPYRIGHT: (C)2012,JPO&INPIT |
