Application
Plastic resins for PET Bottles & Preforms
Bottle-grade PET chips for water, carbonated drinks, edible oil and food containers, specified by intrinsic viscosity.
Typical parts
- Water bottles
- Carbonated soft drink bottles
- Edible oil and sauce bottles
- Hot-fill juice bottles
- Food jars and containers
What the material has to do
- 01Intrinsic viscosity
IV sets bottle strength: about 0.76–0.80 dL/g for water, higher for carbonated drinks.
- 02Low acetaldehyde
Water bottles need low AA to keep a neutral taste.
- 03Clarity and color
Consistent color (b-value) and clarity across lots.
- 04Gas barrier
Carbonated drinks need CO₂ retention over shelf life.

Processing notes
Dry PET to below 50 ppm moisture, typically at 160–170 °C for 4–6 hours, and check the IV drop from chip to preform as part of incoming quality control.
General guidance only; follow the producer's TDS for each grade.

PET Bottles & Preforms: common questions
Can water-bottle grade be used for carbonated drinks?
It is not recommended; carbonated drinks need a higher-IV grade for burst strength.
How is bottle-grade PET packed?
Usually in 1,100–1,250 kg jumbo bags; packing per grade is on its product page.
