    Product Detail

    Product Advantage
    Advantage of High Transparency
    Compared with POF and Cross-linked Shrink Film, the transparency of PEF is much better under the same optical conditions. The packaging effect is excellent, making it ideal for high-end product packaging and suitable for both automatic and semi-automatic packaging machinery.
    Advantage of Low Shrinkage Temperature
    Recommended shrinkage temperature: 135-150℃. (Note: Adjustments should be made based on specific packaging machine temperature and transmission speed).
    Small and Soft Corners
    Compared with traditional POF shrink film, PEF provides a superior shrinking outcome with soft corners and strong sealing. The softness of PEF is increased by approximately 40%. Its performance data is very close to that of cross-linked film, ensuring the corners after shrinking remain small and soft.
    Silicone Oil Test Results
    Outstanding Shrinkage Performance
    In silicone oil tests at 120℃-150℃ film surface temperatures, PEF's shrinkage rate outperforms POF and rivals cross-linked films. At 115°C, PEF reaches a shrinkage rate of over 50%, the highest among the three types, demonstrating excellent low-temperature efficiency.
    Energy Saving Potential
    Energy Saving Potential
    PEF’s excellent low-temperature shrinkage performance offers significant potential cost-saving opportunities for enterprise production by reducing energy consumption during the packaging process.
    Haze Comparison Chart
    Excellent Optical Performance
    With a haze test result of only 2.8%, PEF shrink film demonstrates superior light transmittance—up to 45% higher than that of POF and cross-linked films, ensuring your product's visual clarity.
    Tensile Strength Test
    Excellent Tensile Strength
    The machine direction and transverse direction tensile strength of PEF reaches more than 100 Mpa, providing exceptional tensile properties and flexibility for diverse packaging needs.

    Frequently Asked Questions
    What are the main advantages of PEF shrink film over POF?
    PEF offers significantly higher transparency, lower shrinkage temperatures, and softer corners compared to traditional POF films, making it ideal for high-end retail packaging.
    What is the recommended temperature for shrinking PEF film?
    The suggested shrinkage temperature for PEF is between 135-150℃, though this should be adjusted based on your specific machinery and production speed.
    How does PEF film contribute to energy savings?
    Due to its excellent low-temperature shrinkage performance, PEF allows machines to operate at lower heat settings, which can reduce the overall power consumption of the packaging line.
    Is PEF shrink film compatible with automatic packaging machines?
    Yes, PEF is specifically designed to be suitable for both automatic and semi-automatic packaging machinery, ensuring smooth integration into existing production lines.
    Is this shrink film environmentally friendly?
    Yes, PEF shrink film is recyclable in communities that have established programs and facilities for collecting and recycling plastic films.
    How does the transparency of PEF compare to cross-linked films?
    PEF provides excellent light transmittance that is up to 45% higher than both standard POF and cross-linked films, offering a much clearer view of the packaged product.
