    Product Detail

    Product Advantage

    Advantage of High Transparency

    Compared with POF and Cross-linked Shrink Film, the transparency of PEF is significantly superior under the same optical conditions. The packaging effect is excellent, making it ideal for high-end products and compatible with automatic and semi-automatic packaging machinery.

    Low Shrinkage Temperature

    Suggested Temperature: 135-150℃

    (Note: Adjustments may be required based on specific packaging machine temperature and transmission speed.)

    Small and Soft Corners

    Compared to traditional POF shrink film, PEF delivers a superior shrinking outcome with soft corners and strong sealing. The softness of PEF is increased by approximately 40%. Performance data is very close to cross-linked film, ensuring corners after shrinking remain small and soft.

    Silicone Oil Test Results
    Outstanding Shrinkage Performance

    In silicone oil tests (120℃-150℃), PEF's shrinkage rate exceeds POF and rivals cross-linked films. At 115°C, PEF achieves the highest shrinkage rate among the three types, reaching over 50%, demonstrating excellent low-temperature performance.

    Energy Saving Potential

    PEF's exceptional low-temperature shrinkage performance offers significant potential cost-saving opportunities for enterprise production by reducing energy consumption during the packaging process.

    Energy Saving Performance
    Haze Comparison Chart
    Excellent Optical Performance

    In haze testing, PEF shrink film data is just 2.8%. This indicates excellent light transmittance, which is up to 45% higher than both POF and standard cross-linked films.

    Excellent Tensile Strength

    The machine direction (MD) and transverse direction (TD) tensile strength of PEF reaches more than 100 Mpa, providing superior tensile properties and flexibility for secure packaging.

    Frequently Asked Questions

    1. What makes PEF shrink film different from POF?
    PEF offers significantly higher transparency and better low-temperature shrinkage performance. Its optical performance is up to 45% higher than POF, and it provides softer corners after shrinking.
    2. What is the recommended shrinkage temperature for PEF film?
    The suggested shrinkage temperature is between 135-150℃, though this should be adjusted based on your specific packaging machinery and line speed.
    3. How does PEF contribute to energy saving?
    Due to its excellent low-temperature shrinkage properties, PEF requires less heat to achieve a perfect shrink, which can reduce the power consumption of production lines.
    4. Is PEF shrink film environmentally friendly?
    Yes, PEF is recyclable in communities that have established programs and facilities for collecting and recycling plastic films.
    5. What is the tensile strength of PEF film?
    PEF film boasts high tensile strength, reaching over 100 Mpa in both machine and transverse directions, ensuring durability and flexibility.
    6. Can PEF be used with automatic packaging machines?
    Absolutely. PEF is designed to be suitable for both automatic and semi-automatic packaging machinery, making it versatile for various industrial applications.
