Double Sided Silicone Release Paper — Duplex Silicone Liner
Double sided silicone release paper carries adhesive on both faces — for double-sided tape, foam mounting and two-layer die-cutting — with equal or differential release levels on each side.
- Equal or differential release on the two faces
- Base: glassine or CCK to match your process
- Release force 3-80 g/25mm (±3g) per side
- Factory direct from Shanghai

Single vs Double Sided Release Paper
Choose by application, not by catalogue order.
| Dimension | Single Sided | Double Sided |
|---|---|---|
| Structure | Silicone on one face | Silicone on both faces |
| Carries adhesive | One layer | Two layers (or 1 adhesive + 1 carrier) |
| Typical use | Labels, single-sided tape | Double-sided tape, foam mounting, transfer adhesive |
| Cost | Lower | Higher (double coating + curing) |
| Release levels | One | Equal or differential per face |
Bottom line: Double sided when your product carries adhesive on both faces; single sided for labels and standard tape.

Equal-Level Option
Symmetric release for two-layer laminating.
Process and Testing
Base inspection → first-side silicone coating → curing → second-side coating with independent release control → per-batch release testing on both faces → slitting and rewinding.
Frequently Asked Questions
Can the two faces have different release forces?
Yes — that is differential release. Typical for transfer tapes and two-layer die-cutting; we tune each side within 3-80 g/25mm (±3g).
What is differential release for?
When one adhesive layer must release easily and the other must hold firm — the liner does both jobs in one pass.
Which base should I choose?
Glassine for high-flatness die-cutting; CCK when heat tolerance and economy matter. See glassine or CCK.
