Self-Adhesive Cover Tape Supplier in China - Reliable Factory for High-Quality Adhesive Solutions

,

The Self-Adhesive Cover Tape Series from our China factory employs cutting-edge precision coating technology to deliver stable and controllable adhesion. This innovative solution features a unique ambient-temperature sealing capability, allowing for robust bonding with carrier tapes without the need for heating, thereby streamlining the packaging process and reducing energy costs.

,

Our product line is systematically categorized into four grades to meet diverse bonding strength requirements:
Low Tack (YJLG-80/81): With a peel force of 30-70g, this option is ideal for packaging that necessitates frequent opening.
Medium Tack (YJLG-83/85): Ensuring a peel force of 60-90g, it strikes a perfect balance between seal integrity and ease of opening.
High Tack (YJLG-86/87): Providing a peel force of 70-120g, this grade offers stronger sealing assurance for heightened security.
Super High Tack (YJLG-87+/89): Meeting the most stringent sealing demands, this grade boasts a peel force of 100-150g.

,

All models guarantee consistently excellent mechanical properties, featuring a tensile strength of ≥2.5kg and an elongation of ≥30%, with thickness meticulously controlled within 0.06mm ±0.005mm. As a leading supplier in China, we ensure our self-adhesive cover tapes meet the highest standards for performance and reliability.

    Product Overview: YJLG-80/81 Low-Tack Electronic Tape

    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.

    YJLG-80/81 provides multiple 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.
