Biaxially Oriented Polyester (BOPET) is a type of plastic film made from polyester that has been stretched in two directions, or axes. This process enhances its strength, clarity, and barrier properties, making it suitable for various applications, including packaging, electrical insulation, and photographic films. BOPET is known for its durability and resistance to moisture, chemicals, and UV light. It is often used in food packaging to extend shelf life and maintain freshness. Additionally, its lightweight and flexible nature make it a popular choice in the production of labels and graphics.
