BOPET sheets stand out due to their distinct performance attributes, which stem from the biaxial orientation technique. This process aligns the polymer molecules in two directions, enhancing the material’s overall stability and functionality. Core characteristics include:
Superior Tensile Strength & Durability: Biaxial orientation significantly boosts the sheet’s resistance to tearing, puncturing, and impact, making it ideal for applications requiring long-term structural integrity.
Excellent Optical Clarity: BOPET sheets offer high transparency and gloss, ensuring sharp visibility for packaged products or display purposes. They also maintain clarity even under varying temperature conditions.
Heat Resistance: With a high melting point (typically around 250°C / 482°F), BOPET retains its shape and properties in high-temperature environments, suitable for heat-sealing or sterilization processes.
Chemical & Moisture Barrier: The material exhibits strong resistance to oils, solvents, and water vapor, protecting contents from external contaminants and extending shelf life.
Dimensional Stability: BOPET sheets resist shrinkage or warping, even after exposure to temperature fluctuations, ensuring consistent performance in precision applications.
Printability & Coating Compatibility: Their smooth surface allows for high-quality printing, lamination, or coating (e.g., with aluminum for enhanced barrier properties), expanding their functional versatility.
