    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, ideal for high-end product packaging and suitable for automatic and semi-automatic machinery.

    温Low Shrinkage Temperature

    Shrinkage temperature suggestion: 135-150℃. (Note: Adjustments may be needed based on different packaging machine temperatures and transmission speeds).

    ◰Small and Soft Corners

    Compared with traditional POF shrink film, PEF has better shrinking outcomes with soft corners and strong sealing. The softness of PEF is increased by about 40%, making its performance data very close to that of cross-linked film.

    Silicone Oil Test Results
    ★Outstanding Shrinkage Performance

    In silicone oil tests (120℃-150℃ film surface temperature), PEF's shrinkage rate is superior to POF and close to cross-linked films. At 115°C, PEF reaches a shrinkage rate of over 50%, the highest among the three types, demonstrating excellent low-temperature performance.

    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
    ◎Excellent Optical Performance

    Haze testing shows PEF shrink film at just 2.8%. This indicates excellent light transmittance, which is up to 45% higher than that of both POF and cross-linked films.

    Tensile Strength Test
    ⇅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 diverse applications.

    Frequently Asked Questions

    What are the main advantages of PEF shrink film compared to POF? PEF offers significantly higher transparency (up to 45% better light transmittance), lower shrinkage temperatures, and softer corners compared to traditional POF films.
    What is the recommended shrinkage temperature for PEF film? The suggested shrinkage temperature for PEF is between 135-150℃, though this should be adjusted based on your specific packaging machine speed and environment.
    Does PEF shrink film help in reducing energy costs? Yes. Due to its excellent low-temperature shrinkage performance, it allows machines to operate at lower heat levels, providing energy-saving potential for production lines.
    How does the softness of PEF compare to other films? PEF is approximately 40% softer than traditional POF, resulting in smaller and softer corners after shrinking, which is very similar to the performance of high-end cross-linked films.
    Is PEF shrink film environmentally friendly? Yes, PEF shrink film is recyclable in communities that have established programs and facilities for collecting and recycling plastic films.
    What is the tensile strength of PEF film? PEF exhibits excellent tensile strength in both machine and transverse directions, reaching over 100 Mpa, ensuring durability and flexibility.
