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

,

Introducing the Self-Adhesive Cover Tape Series, a product meticulously crafted by leading China suppliers utilizing advanced precision coating technology. This series is designed to ensure stable and controllable adhesion, addressing the needs of various packaging processes.

,

With its innovative ambient-temperature sealing characteristic, the tape bonds firmly with carrier tapes without the need for heating. This feature not only simplifies the packaging process but also significantly reduces energy consumption costs, making it an ideal choice for factories looking to enhance efficiency.

,

The tape is scientifically categorized into four grades based on specific bonding strength requirements:
Low Tack (YJLG-80/81): Offers a peel force of 30-70g, perfect for applications requiring frequent opening.
Medium Tack (YJLG-83/85): Provides a peel force of 60-90g, striking a perfect balance between seal integrity and ease of opening.
High Tack (YJLG-86/87): Ensures a peel force of 70-120g for stronger sealing assurance.
Super High Tack (YJLG-87+/89): Meets the most stringent sealing requirements with a peel force of 100-150g.

,

Each model maintains outstanding mechanical properties: tensile strength ≥2.5kg and elongation ≥30%, with a precise thickness controlled within 0.06mm ±0.005mm. Trust in our high-quality products from China suppliers to meet your industrial sealing needs.

    💬 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 provides sufficient bonding strength during the encapsulation process while enabling clean, residue-free removal. This makes it ideal for precision components where surface cleanliness is critical.
    Q What 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 select the appropriate grade based on the electrostatic sensitivity of their specific components.
    Q Can YJLG-80/81 be ordered in custom widths?
    Yes. While the standard specification covers widths from 5.4mm to 97.5mm, custom sizes are fully supported. Please contact our team with your specific dimensional requirements for a tailored solution.
    Q Is YJLG-80/81 suitable for use with flexible circuit boards (FPCs)?
    Yes. YJLG-80/81 is widely used in light encapsulation scenarios including LEDs and flexible circuit boards (FPCs), where a balance of adhesion strength, thin profile, and electrostatic protection is essential.
    Q How does the thickness tolerance of YJLG-80/81 affect performance?
    The tape maintains a precise thickness of 0.06mm with a tight tolerance of ±0.005mm. This consistency ensures uniform performance across the entire roll, preventing issues such as uneven adhesion or mechanical stress during automated high-speed mounting processes.
    Q What mechanical properties does YJLG-80/81 offer to prevent tape breakage?
    YJLG-80/81 delivers a tensile strength of ≥2.5kg and an elongation rate of ≥30%. These mechanical properties ensure the tape can withstand the tension and stretching forces encountered during high-speed automated mounting and transportation without breaking or deforming.
