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

,

Introducing the Self-Adhesive Cover Tape Series, a product crafted by leading China manufacturers utilizing advanced precision coating technology. This series ensures stable and controllable adhesion, making it an essential choice for various packaging applications. Its remarkable ambient-temperature sealing feature enables secure bonding with carrier tapes without the need for heating. This innovation significantly streamlines the packaging process, ultimately lowering energy consumption costs.

,

Our self-adhesive cover tapes are scientifically categorized into four grades based on bonding strength requirements:
Low Tack (YJLG-80/81): With a peel force ranging from 30-70g, this grade is ideal for packaging that requires frequent opening.
Medium Tack (YJLG-83/85): Offering a peel force of 60-90g, it strikes a perfect balance between seal integrity and ease of access.
High Tack (YJLG-86/87): Designed for strength, this grade provides a peel force of 70-120g, ensuring superior sealing assurance.
Super High Tack (YJLG-87+/89): Meeting the most stringent sealing demands, it boasts a peel force of 100-150g.

,

Every model in our range maintains consistently excellent mechanical properties, with a tensile strength of ≥2.5kg and elongation of ≥30%. The thickness is meticulously controlled within 0.06mm ±0.005mm, making us one of the top suppliers in the industry.

    ⚡ Anti-Static Protection

    YJLG-80/81 is a low-adhesion electronic tape specifically designed for applications requiring gentle bonding and easy peeling. With a peel adhesion force controlled between 30–70 grams, it ensures effective bonding during the encapsulation process while allowing easy removal when needed, leaving no residue—making it particularly suitable for precision component encapsulation that demands high surface cleanliness.

    The product features a uniform thickness of 0.06mm (tolerance ±0.005mm), maintaining a slim profile while offering excellent mechanical properties—tensile strength ≥2.5kg and elongation ≥30%—ensuring it resists breakage or deformation during high-speed mounting and transportation.

    ⚡ Anti-Static Grade Options
    • Single-Sided Brown — Anti-static performance: 10⁵–10⁸ Ω
    • Single-Sided Light Blue — Anti-static performance: 10⁶–10¹⁰ Ω
    • Double-Sided Anti-Static — Anti-static performance: 10⁶–10¹¹ Ω

    Users can flexibly select based on the electrostatic sensitivity of their components. Its standard specifications cover widths ranging from 5.4mm to 97.5mm, and custom sizes are also supported. It is widely used in light encapsulation scenarios such as LEDs and flexible circuit boards, where both adhesion strength and electrostatic protection are critical.

    ❓ Frequently Asked Questions
    Q What is the peel force range of YJLG-80/81, and why does it matter?
    The YJLG-80/81 has a peel adhesion force of 30–70 grams. This low-tack range is carefully controlled to ensure the tape bonds effectively during the encapsulation process, yet can be removed cleanly and easily without leaving any adhesive residue—critical for maintaining the surface cleanliness of precision electronic components.
    Q What anti-static grades are available, and how do I choose the right one?
    Three anti-static grades are available: single-sided brown (10⁵–10⁸ Ω), single-sided light blue (10⁶–10¹⁰ Ω), and double-sided anti-static (10⁶–10¹¹ Ω). Selection should be based on the electrostatic sensitivity (ESD sensitivity level) of your components—more sensitive components typically require a lower surface resistance grade for stronger protection.
    Q Does YJLG-80/81 support custom width sizes?
    Yes. While the standard width range covers 5.4mm to 97.5mm, custom sizes are fully supported to accommodate specific production line requirements or unique component dimensions. Please contact the supplier with your specifications for a tailored solution.
    Q Is YJLG-80/81 suitable for high-speed automated mounting processes?
    Yes. With a tensile strength of ≥2.5 kg and elongation of ≥30%, the tape is engineered to withstand the mechanical stresses of high-speed mounting and transportation without breaking or deforming, ensuring consistent performance in automated production environments.
    Q What types of products is YJLG-80/81 most commonly used for?
    YJLG-80/81 is widely used in light encapsulation applications including LEDs and flexible circuit boards (FPCs). It is especially suitable for scenarios where both controlled adhesion strength and reliable electrostatic protection are required to safeguard sensitive electronic components.
    Q What is the thickness tolerance of YJLG-80/81, and why is it important?
    The tape maintains a uniform thickness of 0.06mm with a tight tolerance of ±0.005mm. This precision is essential in electronics manufacturing where consistent tape thickness directly affects component alignment, encapsulation uniformity, and overall assembly quality in high-precision applications.
