PET vs PETG vs Polycarbonate (PC) Bottles

What bottles are best suited for your application?

  • PET (Polyethylene Terephthalate) is good for most applications but lacks a gas barrier, so long-term storage in PET can be “iffy.”
  • PETG (Polyethylene Terephthalate Glycol) has glycol in it which acts as a gas barrier. This makes them better suited for long term storage (i.e. buffers, cell media, etc.)
  • Polycarbonate (PC) is the strongest of the three plastics and is used for freezing applications (-20 C).
