(57) [Summary] [PROBLEMS] To provide excellent transparency, moldability, and heat and humidity resistance for food containers that are sterilized and disinfected at relatively high temperature in blister packages and containers, and for high-temperature and high-humidity lighting equipment covers such as bathrooms. Develop a polyester resin multilayer sheet and molded product. SOLUTION: A specific formulation and a sheet constitution, that is, a skin layer in which the naphthalenedicarboxylic acid component in the acid component is 5 to 3 A polyester resin comprising 5% by weight of a polyethylene naphthalate resin having a terephthalic acid component of 65 to 95% by weight, a core layer comprising a polyethylene terephthalate resin, and a weight ratio of the skin layer in the sheet being 10 to 30% by weight. The problem can be solved by a multilayer sheet and a molded product thereof. |
