Self-Adhesive Cover Tape from China Factory - High-Quality Suppliers for Efficient Packaging Solutions

,

Introducing the Self-Adhesive Cover Tape Series, a revolutionary product that employs advanced precision coating technology, ensuring stable and controllable adhesion. Our unique ambient-temperature sealing feature allows for strong bonding with carrier tapes without the need for heating, streamlining the packaging process while significantly cutting energy costs.

,

This innovative tape is categorized into four grades based on bonding strength, making it suitable for various applications:
Low Tack (YJLG-80/81): With a peel force of 30-70g, this grade is ideal for packaging that requires frequent access.
Medium Tack (YJLG-83/85): Offering a peel force of 60-90g, it strikes a perfect balance between seal integrity and ease of opening.
High Tack (YJLG-86/87): This version delivers a peel force of 70-120g, ensuring a robust sealing solution.
Super High Tack (YJLG-87+/89): Designed for the most demanding sealing needs, it provides a peel force of 100-150g.

,

All models exhibit consistently outstanding mechanical properties, with a tensile strength of ≥2.5kg and elongation of ≥30%. Our tapes are manufactured in China by top suppliers and factories, with thickness precisely controlled at 0.06mm ±0.005mm, guaranteeing quality and performance.

    ❓ Frequently Asked Questions
    QWhat is the peel force range of YJLG-80/81, and why does it matter?
    YJLG-80/81 has a peel adhesion force of 30–70 grams. This low-tack range ensures the tape holds components securely during the encapsulation process while allowing clean, residue-free removal afterward—critical for maintaining surface cleanliness on precision electronic components.
    QWhat anti-static grades are available for YJLG-80/81?
    Three anti-static options are available: single-sided brown (10⁵–10⁸Ω), single-sided light blue (10⁶–10¹⁰Ω), and double-sided anti-static (10⁶–10¹¹Ω). Users can choose the appropriate grade based on the electrostatic sensitivity of their specific components.
    QCan YJLG-80/81 be customized to non-standard widths?
    Yes. While the standard width range covers 5.4mm to 97.5mm, fully custom sizes are supported to accommodate specific production line or component requirements.
    QWhat are the key mechanical properties of this tape?
    YJLG-80/81 offers a tensile strength of ≥2.5kg and an elongation of ≥30%, combined with a uniform 0.06mm thickness (±0.005mm tolerance). These properties ensure the tape withstands high-speed mounting and transportation without breaking or deforming.
    QWhat industries and applications is YJLG-80/81 best suited for?
    It is widely used in light encapsulation applications including LED packaging and flexible circuit board (FPC) manufacturing, where both reliable adhesion and effective electrostatic protection are essential requirements.
    QDoes YJLG-80/81 leave any adhesive residue after removal?
    No. YJLG-80/81 is specifically engineered to peel away cleanly without leaving any adhesive residue on component surfaces, making it ideal for high-cleanliness precision encapsulation processes.
