Core Technical Performance Features

Precision Controlled Release Force

Customizable light / medium / heavy release force (3g/25mm - 500g/25mm), ultra-low batch deviation (≤±5%), stable stripping performance for pressure-sensitive adhesives (PSA), no adhesive transfer, no liner tearing or residue left.

Premium Optical Properties

High light transmittance (≥90%), low haze value, mirror-flat surface finish, ideal for visual defect inspection, transparent lamination, optical adhesive protection and high-definition printing applications.

Extreme Thermal Stability

Wide operating temperature range (-40°C to 150°C), no thermal shrinkage, warping or performance degradation during high-temperature curing, hot lamination, coating and drying processes.

Uniform Silicone Coating Layer

Adopts gravure coating & micro-conformal coating technology, monolithic thickness consistency, no air bubbles, missing coating or pinholes, ensuring consistent release performance across the entire roll.

High Mechanical & Dimensional Stability

Exceptional tensile strength, low elongation at break, minimal longitudinal/transverse shrinkage rate, anti-wrinkle and anti-deformation, compatible with high-speed automated converting, slitting and die cutting lines.

Strong Environmental & Chemical Resistance

Excellent resistance to chemical solvents, moisture, oil and UV radiation, maintaining stable performance during long-term storage, transportation and harsh outdoor applications, preserving adhesive integrity.
