BOPET, or Biaxially Oriented Polyethylene Terephthalate, is a type of plastic film made from polyester. It is created by stretching the film in both the machine and transverse directions, which enhances its strength, clarity, and barrier properties. BOPET is commonly used in packaging, electrical insulation, and as a substrate for various applications. This material is known for its excellent durability and resistance to moisture, chemicals, and UV light. BOPET films are often used in the food industry for packaging, as well as in the production of solar panels and electronic devices. Its versatility makes it a popular choice in many sectors.
