PET
PET for bottle and thermoforming applications.
Polyethylene terephthalate (PET) is the standard material for beverage bottles and thermoformed packaging thanks to its clarity, gas barrier and strength. Bottle grade and sheet/thermoforming grade are supplied separately; R-PET options are available.
Typical Technical Properties
- Types
- Bottle grade (IV 0.76–0.84), sheet/thermoforming grade, fibre grade
- Density
- 1.33–1.40 g/cm³
- Intrinsic viscosity (IV)
- 0.60 – 0.86 dl/g
- Melting point
- 245–260 °C
- Drying
- 160–170 °C for 4–6 h before processing
Values are typical industry ranges; the producer's lot-specific TDS/MSDS is binding.
Applications
- Water, CSD and oil bottles (preforms)
- Thermoformed food cups and trays
- Cosmetic and detergent bottles
- Sheet and blister
- Polyester fibre and strapping
Frequently Asked Questions
Why does the IV value matter?
Intrinsic viscosity reflects molecular weight. High IV (0.80+) is preferred for carbonated bottles, medium (0.76–0.80) for water, lower for sheet.
Must PET be dried before processing?
Yes. PET absorbs moisture; processing it wet lowers IV and makes the product brittle. Moisture ≤ 50 ppm is recommended.
Is food-approved R-PET available?
Yes, we can supply food-contact-approved R-PET grades; simply state it in your request.
