1. A thermoformed article comprising a polymer film and having one or more thermoformed cavities contained therein, wherein the polymer film comprises a polymer blend of 50 wt % to 95 wt % of amorphous polyethylene terephthalate (APET) and 5 wt % to 50 wt % of a copolyester that comprises (a) dicarboxylic acid residues comprising polyethylene terephthalate residues and (b) diol residues comprising (i) ethylene glycol residues and (ii) one or more additional diol monomer residues selected from neopentyl glycol residues, 1,4-cyclohexanedimethanol residues, or diethylene glycol residues, wherein the polymer film exhibits a crystallization time at 120° C. of at least 2.5 minutes as measured by differential scanning calorimetry (DSC).
