Wholesale Self-Adhesive Cover Tape Supplier, Factories

The Self-Adhesive Cover Tape Series utilizes advanced precision coating technology to achieve stable and controllable adhesion. Its unique ambient-temperature sealing characteristic allows for firm bonding with carrier tapes without heating, significantly simplifying the packaging process and reducing energy consumption costs.

Scientifically categorized into four grades based on bonding strength requirements:
Low Tack (YJLG-80/81): Peel force of 30-70g, suitable for packaging requiring frequent opening.
Medium Tack (YJLG-83/85): Peel force of 60-90g, balancing seal integrity with opening convenience.
High Tack (YJLG-86/87): Peel force of 70-120g, providing stronger sealing assurance.
Super High Tack (YJLG-87+/89): Peel force of 100-150g, meeting the most stringent sealing requirements.

All models maintain uniformly excellent mechanical properties: tensile strength ≥2.5kg, elongation ≥30%, with thickness precisely controlled within 0.06mm ±0.005mm.

Product Description

Low Tack (YJLG-80/81)
Model Peel Force (g) Tensile Strength (kg) Elongation (%) Thickness (mm) Specifications (mm)
