摘要： 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.
