Wireless polymeric twist tie

The method of claim,wherein the thermoplastic copolyester is a glycol-modified or acid-modified copolyester that comprises a terephthalic group.

A method of making a twist tie, the method comprising:

• preparing a composition, the composition comprising a thermoplastic copolyester and an ethylene-based copolymer, the ethylene-based copolymer being ethylene vinyl acetate, ethylene acrylic acid, ethylene ethyl acrylate, ethylene methyl acrylate, or any of these in any combination;
• and
• shaping the composition to form the twist tie.

A method of making a twist tie, the method comprising:

• preparing a composition, the composition comprising a thermoplastic copolyester;
• and
• shaping the composition to form the twist tie, the twist tie exhibiting an elongation at breakage of about 100 percent or more, a tensile strength at yield of about 7,000 psi or more, and a tensile strength at breakage of about 8,000 psi or more, when analyzed according to the ASTM D-638-99 standard.

A method of making a twist tie, the method comprising:

• preparing a composition, the composition comprising a thermoplastic copolyester;
• and
• shaping the composition to form the twist tie, the twist tie exhibiting an elongation at breakage of about 300 percent or more, a tensile strength at yield of about 8,000 psi or more, or a tensile strength at breakage of about 10,000 psi or more, when analyzed according to the ASTM D-638-99 standard.
