Our product range is scientifically categorized into four grades, catering to varying bonding strength requirements:
Low Tack (YJLG-80/81): With a peel force of 30-70g, this grade is ideal for applications that require frequent opening.
Medium Tack (YJLG-83/85):Offering 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 ensures enhanced sealing assurance.
Super High Tack (YJLG-87+/89):With a peel force ranging from 100-150g, it meets the most demanding sealing standards.

,

All models exhibit consistently superior mechanical properties: with a tensile strength of ≥2.5kg and elongation of ≥30%. Each tape's thickness is meticulously controlled at 0.06mm ±0.005mm, ensuring exceptional quality. As leading suppliers and manufacturers in China, we are committed to providing the best adhesive solutions for your packaging needs.
