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

,

Introducing our Self-Adhesive Cover Tape Series, engineered with advanced precision coating technology for reliable and controllable adhesion. This innovative tape features unique ambient-temperature sealing properties, allowing for strong bonding with carrier tapes without the need for heating. This not only streamlines the packaging process but also significantly lowers energy consumption costs, making it an ideal choice for eco-conscious businesses.

,

Our Cover Tape Series is scientifically classified into four distinct grades, tailored to meet varying bonding strength requirements:
Low Tack (YJLG-80/81): Offers a peel force of 30-70g, perfect for applications where frequent opening is necessary.
Medium Tack (YJLG-83/85): Provides a peel force of 60-90g, striking the right balance between seal integrity and ease of access.
High Tack (YJLG-86/87): Delivers a peel force of 70-120g, ensuring stronger sealing performance.
Super High Tack (YJLG-87+/89): Meets the most demanding sealing requirements with a peel force of 100-150g.

,

All models in our series maintain consistently excellent mechanical properties, featuring a tensile strength of ≥2.5kg and elongation of ≥30%. Additionally, our tape thickness is meticulously controlled at 0.06mm ±0.005mm. We are proud to be among the leading suppliers and manufacturers of adhesive solutions in China, committed to delivering unmatched quality and performance in every roll.

    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
    What is the peel force range of the YJLG-80/81 tape, and what does it mean for my application?
    The YJLG-80/81 has a peel force of 30–70 grams, classifying it as a low-tack tape. This means it provides sufficient adhesion to hold components securely during the encapsulation process while still allowing clean, easy removal without leaving any adhesive residue on sensitive surfaces.
    Will the YJLG-80/81 tape leave residue after removal?
    No. The YJLG-80/81 is specifically engineered for residue-free removal. Its low-tack adhesive formula ensures that after peeling, component surfaces remain clean — a critical requirement for precision electronics and high-cleanliness manufacturing environments.
    Which anti-static grade should I choose for my components?
    The choice depends on the electrostatic sensitivity (ESD sensitivity) of your components. For moderately sensitive components, the single-sided brown version (10⁵–10⁸ Ω) is suitable. For higher sensitivity, choose the single-sided light blue (10⁶–10¹⁰ Ω) or double-sided anti-static version (10⁶–10¹¹ Ω) for maximum protection.
    Can the YJLG-80/81 tape withstand high-speed automated mounting processes?
    Yes. With a tensile strength of ≥2.5 kg and elongation of ≥30%, the tape is designed to resist breakage and deformation under the mechanical stresses of high-speed mounting and transportation, ensuring reliable performance in automated production lines.
    What standard widths are available, and can I order custom sizes?
    The YJLG-80/81 is available in standard widths ranging from 5.4mm to 97.5mm to cover most common application requirements. Custom sizes are fully supported, allowing you to specify exact dimensions to match your production line or component packaging needs.
    What are the typical applications for the YJLG-80/81 low-tack electronic tape?
    The YJLG-80/81 is widely used in light encapsulation scenarios including LED component packaging and flexible circuit board (FPC) assembly. It is ideal for any application where both reliable temporary adhesion and effective electrostatic protection are required during manufacturing and handling.
