Self-Adhesive Cover Tape from China Suppliers and Factory - High Tack to Low Tack for Efficient Packaging Solutions

,

Introducing the Self-Adhesive Cover Tape Series, a premier product from trusted China Suppliers. This series leverages advanced precision coating technology to deliver stable and controllable adhesion, making it a perfect choice for various applications. Its unique ability to seal at ambient temperatures allows for secure bonding with carrier tapes without the need for heating, which streamlines the packaging process while significantly reducing energy costs.

,

Our tapes are scientifically categorized into four distinct grades based on bonding strength requirements:
Low Tack (YJLG-80/81): With a peel force of 30-70g, this grade is ideal for packaging that requires frequent opening.
Medium Tack (YJLG-83/85): Featuring a peel force of 60-90g, it offers a perfect balance between seal integrity and ease of opening.
High Tack (YJLG-86/87): This grade provides a peel force of 70-120g, ensuring stronger sealing assurance for demanding applications.
Super High Tack (YJLG-87+/89): With a peel force of 100-150g, it meets the most stringent sealing requirements, perfect for critical packaging needs.

,

All models of our self-adhesive cover tapes maintain excellent mechanical properties, with a tensile strength of ≥2.5kg and elongation of ≥30%. Each tape's thickness is precisely controlled within 0.06mm ±0.005mm, ensuring consistent quality you can trust from our Factory in China.

    ❓ Frequently Asked Questions
    Q What makes YJLG-80/81 suitable for precision component encapsulation?
    YJLG-80/81 is engineered with a low peel adhesion force of 30–70 grams, which ensures reliable bonding during the encapsulation process while enabling clean, residue-free removal. This makes it ideal for precision components that require high surface cleanliness, such as LEDs and flexible circuit boards.
    Q Does YJLG-80/81 leave any adhesive residue after removal?
    No. YJLG-80/81 is specifically designed for clean peeling. When removed, it leaves no adhesive residue on the component surface, ensuring the surface integrity and cleanliness required in sensitive electronic assembly environments.
    Q What anti-static grades are available, and how do I choose the right one?
    YJLG-80/81 offers three anti-static options: single-sided brown (10⁵–10⁸Ω), single-sided light blue (10⁶–10¹⁰Ω), and double-sided anti-static (10⁶–10¹¹Ω). Selection depends on the electrostatic sensitivity of your components—the higher the sensitivity, the higher the resistance range you should choose for maximum ESD protection.
    Q Can YJLG-80/81 be ordered in custom widths?
    Yes. While the standard width range covers 5.4mm to 97.5mm, custom sizes are fully supported. You can contact the manufacturer to specify your required dimensions based on your production or application needs.
    Q Is YJLG-80/81 suitable for high-speed automated mounting processes?
    Yes. With a tensile strength of ≥2.5kg and elongation of ≥30%, YJLG-80/81 is designed to withstand the mechanical stresses of high-speed mounting and transportation without breaking or deforming, making it well-suited for automated production lines.
    Q What industries or applications is YJLG-80/81 primarily used in?
    YJLG-80/81 is widely used in light encapsulation scenarios including LED packaging, flexible circuit board (FPC) manufacturing, and other precision electronics assembly applications where both controlled adhesion strength and reliable electrostatic protection are essential.
