Polyethylene Terephthalate (PET or PETE)
Polyethylene Terephthalate (PET or PETE)
PET is a strong, lightweight plastic widely used for its clarity and barrier properties. It is best known for its use in beverage bottles and food containers. It offers excellent resistance to moisture, gases, and impact. PET is also recyclable and used in both fiber and film applications.
- Excellent clarity and strength
- Great gas and moisture barrier
- 100% recyclable
- Safe for food and beverage contact
• Water and soda bottles
• Food jars and clamshells
• Films and sheets
• Textiles (polyester fibers)
