Self-Adhesive Cover Tape from China Suppliers - Factory-Direct High-Quality Adhesive Solutions

,

Introducing our Self-Adhesive Cover Tape Series, a product developed using advanced precision coating technology to ensure stable and controllable adhesion. This innovative tape features a unique ambient-temperature sealing characteristic, allowing for strong bonding with carrier tapes without the need for heating. This not only simplifies the packaging process but also significantly reduces energy consumption costs, making it an efficient choice for businesses.

,

Our product line is scientifically categorized into four distinct grades based on bonding strength requirements, suitable for various applications:

,

Low Tack (YJLG-80/81): With a peel force of 30-70g, this grade is perfect for packaging that requires frequent opening. Ideal for businesses looking for convenience.

,

Medium Tack (YJLG-83/85): Balancing seal integrity with ease of opening, this grade features a peel force of 60-90g, making it versatile for a range of packaging needs.

,

High Tack (YJLG-86/87): Offering a stronger sealing assurance with a peel force of 70-120g, this option is designed for more demanding applications.

,

Super High Tack (YJLG-87+/89): Meeting the most stringent sealing requirements, this grade boasts a peel force of 100-150g, ensuring maximum reliability.

,

All our models maintain uniformly excellent mechanical properties, featuring a tensile strength of ≥2.5kg and elongation of ≥30%. The thickness is precisely controlled within 0.06mm ± 0.005mm, ensuring consistent performance. As a leading factory and supplier in China, we are committed to providing high-quality self-adhesive cover tapes tailored to your specific needs.
