An object of the present invention is to more conveniently provide a copolyester for a polyester film which exhibits excellent dimensional stability and in particular excellent dimensional stability against environmental changes in, for example, temperature and humidity, and has a small film elongation percentage at 110° C. A copolyester of the present invention comprises: (A) an aromatic dicarboxylic acid component; (B) an alkylene glycol component; and (C1) a dimer acid component and/or (C2) a dimer diol component, wherein the copolyester contains, with reference to a molar number of a total dicarboxylic acid component, 0.5 to 3.5 mol % of the dimer acid component (C1) and/or 0.3 to 5.0 mol % of the dimer diol component (C2).

In various aspects, the present disclosure pertains to thermoformed webs that comprise polymer films having one or more thermoformed cavities contained therein, the polymer films comprising a polymer blend of amorphous polyethylene terephthalate (APET) and a copolyester that comprises (a) dicarboxylic acid residues (e.g., dicarboxylic acid residues that comprise terephthalic acid residues and, optionally, one or more additional dicarboxylic acid residues) and (b) diol residues (e.g., diol residues comprising ethylene glycol residues and, optionally, one or more additional diol monomer residues). Other aspects of the disclosure pertain to methods of forming such thermoformed webs, packaged products comprising such thermoformed webs, and methods of recycling such thermoformed webs.
