What Is Double PE & Double Silicone PE-Coated Release Liner？

Double PE & Double Silicone refers to a high-performance structure of PE-coated release liner, widely adopted in high-end adhesive tapes and electronic precision applications.

Structure of Double PE & Double Silicone

Double PE & Double Silicone release liners are made via two key steps: applying a protective PE “raincoat” and a functional silicone release layer.

Double PE – The Protective “Raincoat”

Base papers such as kraft paper and glassine paper have uneven surfaces. Direct silicone coating will penetrate the paper. Double PE means a uniform polyethylene film is laminated on both sides of the base paper. This film acts as a smooth, dense barrier to prevent silicone penetration and prepare for the coating process.

Double Silicone – The Release Layer

Double Silicone means high-performance release agent is coated on both sides of the PE‑laminated paper. This treatment provides reliable non‑stick and easy‑release performance on both surfaces.

Common Structures

Single PE & Single Silicone: PE lamination and silicone coating on one side only.

Double PE & Single Silicone: PE lamination on both sides, but silicone coating on one side only.

Double PE & Double Silicone vs. Single PE & Single Silicone

Comparison	Double PE & Double Silicone	Single PE & Single Silicone
Structure	PE lamination + silicone coating on both sides	PE lamination + silicone coating on one side only
Properties	High stability, tear-resistant, moisture-proof, anti-curl	Relatively lower strength and stability
Cost	Higher	Lower
Applications	Double-sided tapes, foam tapes, precision electronic die-cutting	Labels, daily necessities, standard tapes

Advantages & Applications of Double-Side Coating

Superior dimensional stability: Symmetrical treatment balances internal stress, ensuring flatness and anti-curl for high-precision processing.
Strong physical performance: PE film delivers excellent waterproofing, tear resistance and chemical stability.
Flexible release control: Dual-side coating supports customized release force on each side for complex production.
Widely used in: double-sided adhesive tapes, high-performance foams, precision electronic die-cutting and high-accuracy printing.
