Process for making recyclable copolyesters articles with living hinges

A process for producing a recyclable article comprising

• A) producing component A—a reclosable lid with a living hinge as a single component by injection molding at least one polyester using a mold with one or more injection points wherein the average polyester flow length divided by the average thickness of the lid is below 200;
• wherein at least one polyester comprises:
• (a) a dicarboxylic acid component comprising:
• (i) 88 to 100 mole % of terephthalic acid residues;
• (ii) 0 to 12 mole % of aromatic and/or aliphatic dicarboxylic acid residues having up to 20 carbon atoms;
• and
• (b) a glycol component comprising:
• (i) 88 to 100 mole % of ethylene glycol residues;
• and
• (ii) 0 to 12 mole % of 1,4-cyclohexanedimethanol residues;
• wherein the total mole % of the acid residues is 100 mole %, and the total mole % of the glycol residues is 100 mole %;
• wherein the inherent viscosity (IhV) of said polyester ranges from 0.60 to 1.1 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.25 g/50 ml at 25° C.;
• and
• wherein the melting point temperature (Tm) of said polyester ranges from 225 to 255° C. as determined by ASTM D3418 at a scan rate of 10° C./min;
• B) producing component B—a container by injection stretch blow molding at least one polyester;
• wherein at least one polyester comprises:
• (a) a dicarboxylic acid component comprising:
• (i) 88 to 100 mole % of terephthalic acid residues;
• (ii) 0 to 12 mole % of aromatic and/or aliphatic dicarboxylic acid residues having up to 20 carbon atoms;
• and
• (b) a glycol component comprising:
• (i) 88 to 100 mole % of ethylene glycol residues;
• and
• (ii) 0 to 12 mole % of 1,4-cyclohexanedimethanol residues;
• and
• (c) optionally at least one branching agent in the amount ranging from 0.1 to 1.0 mole % based on the total moles of glycol residues if said branching agent has hydroxyl substituents and otherwise based on the total moles of acid residues;
• wherein the total mole % of the acid residues is 100 mole %, and the total mole % of the glycol residues is 100 mole %;
• wherein the inherent viscosity (IhV) of said polyester ranges from 0.60 to 1.1 dl/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.25 g/50 ml at 25° C.;
• and wherein the melting point temperature (Tm) of said polyester ranges from 225 to 255° C. as determined by ASTM D3418 at a scan rate of 10° C./min.
