The Science of Strength: Inside the BOPET Film Stretching Process
How Biaxial Orientation and Heat Setting Transform Basic Resin into High-Performance Polyester Film Product Overview When engineers compare standard PET to BOPET, the difference in performance is night and day. Standard PET is brittle and lacks tensile strength, while BOPET is incredibly tough, optically clear, and dimensionally stable. The secret behind this transformation lies entirely
