At the same time, the application of PTA is concentrated, more than 90% of PTA in the world is used in the production of polyethylene terephthalate (PET). It takes 0.85-0.86ton PTA to produce 1 ton PET and 0.33-0.34 ton of MEG (ethylene glycol). Polyesters include fiber chips, polyester fibers, bottles slices and film sections. In the domestic market, 75% of PTA is used to produce polyester fibers and 20% is used to produce bottle grade polyester, which is mainly used in the packaging of various beverages, especially carbonated beverages; 5% for membrane grade polyester, mainly applied to packaging materials, film and tape.
