Abstract
A polyester laminate including at least one polyester layer C and at least one layer selected from the group consisting of a resin layer D and a paper layer E. The polyester layer C is made of a polyester resin A in which from 5 to 80 mol % of the total diol units is a diol unit having a cyclic acetal structure. The resin layer D is made of a resin other than the polyester resin A. At least one surface layer of the polyester laminate is the resin layer C. The polyester laminate is particularly suited as a container for preserving food because of its excellent heat sealability and high fragrance preservation.
